Controllers & Testings
Use aquarium controllers, monitors and test kits to measure key water parameters.
Hobbyists usually perform water changes, dose aquarium supplements and replace their filter media to keep water conditions at optimum levels. But how do you know when it’s time to perform each of these activities? The answer is simple: by testing your water.
The most popular and affordable way to test your aquarium water quality is by using an aquarium test kit. Most aquarium test kits use the titration method to determine the concentration of the parameter you are testing. For a fish-only saltwater aquarium, you should test pH, Alkalinity, Ammonia, Nitrite and Nitrate. For a reef tank, you’ll want to test the Calcium, Magnesium and Phosphate levels in your tank in addition to the aforementioned parameters.
Since frequent testing can get tedious, many hobbyists supplement their regular testing regimen with an aquarium controller or monitor. An aquarium controller will not only provide you with constant temperature, pH, ORP and salinity readings, you can also use it to control your lights, pumps and even alert you if something goes awry. The Neptune Systems Apex AquaController and Digital Aquatics ReefKeeper have been the industry leaders in total aquarium control for quite some time.
American Marine Pinpoint aquarium monitors are another option to consider. Unlike the full-featured controllers offered by Neptune Systems and Digital Aquatics which offer the ability to track several parameters, each device in the Pinpoint series only monitors one, such as pH, Calcium, Nitrate or salinity.
Most marine aquarium owners use a combination of testing tools to monitor water quality. Test kits, thermometers and refractometers are standard tools every reef tank owner utilizes. As your aquarium matures and its inhabitants grow, maintaining steady water parameters becomes more challenging. That is usually when a more sophisticated controller or monitor comes into play since they help simplify the daily and weekly chores required to keep water parameters within ideal ranges.

FAUNA MARIN AquaHomeTest KH - 50 TESTS
$35.00
The carbonate hardness (KH) or alkalinity* of a water sample characterises the buffering capacity, i.e. the ability to maintain the pH value of the water. It is primarily defined by the proportion of hydrogen carbonate ions in the water. As the pH value increases, other basic ions such as the hydroxide ions also contribute to the alkalinity. The alkalinity should be tested in all aquariums regularly. If the alkalinity in the aquarium is too low, the pH value can sink (sudden drop in acidity) to a level which is life-threatening for many fish and invertebrates. In reef aquariums, an adequate alkalinity is essential for strong coral growth. On the other hand, an overly high alkalinity in saltwater tanks can lead to lime precipitates and also have a negative impact on coral growth.
*There are many terms in water chemistry to describe the buffering capacity with varying definitions. The term “carbonate hardness” is customary in reef- and fishkeeping; however, it is the alkalinity which is measured. In this test, both terms are used synonymously. The reading for alkalinity is usually given in degrees of German hardness (°dKH). You can find a table for converting this unit into other common units (such as the equivalence unit millival per litre (mval/l) or the volume of substance in mmol/l) on the second cover page.
Natural seawater has an alkalinity of 6.5 °dKH. The alkalinity in saltwater aquariums should range from 6 to 9 °dKH.
Ask your specialist retailer for the correct alkalinity for your tank.
How to correct unfavourable values:
To increase the alkalinity when levels are too low, we recommend using Fauna Marin Carbonate MIX or Fauna Marin Easy dKH.

ApexEL
$780.00
Having a great aquarium just got easier…. and more affordable!
Introducing the new Neptune Systems ApexEL, the “Entry Level” Apex.
Maintain your aquarium with ease. The ApexEL monitors key parameters like temperature, pH, and the status of your connected equipment. Proper monitoring helps reduce the risk of losing your aquatic pets from parameter swings or failed equipment.
At a lower cost than its big brother, the Apex, the ApexEL shares almost all the features of the flagship Apex, with the exception that it does not have built-in ORP, salinity monitoring, or 0-10V ports.
The ApexEL is expandable with modules and probes, if desired in the future.
Wireless Internet-Ready
The ApexEL connects to your network via wire, or, the built in 802.11g/n Wi-Fi.
Easy Setup
Set up tasks and to-do reminders help guide you through configuring everything from temperature control, trouble alerts to your mobile device, and many other common aquarium tasks. With the ApexEL, an aquarium controller no longer requires an advanced degree — you are up and running in 5 EASY STEPS:
Mount it to the wall or inside your cabinet
Plug in the probes and your equipment
Connect it to your home network via wi-fi or cable
Run the new Configuration Wizards
Get the basics of monitoring and control for your entire tank set up, in less than 15 minutes, with no programming!
Self Contained Monitoring
Every ApexEL has a built-in, completely functional, web server – even when the internet is down. Your tank will continue to operate without interruption and can still be controlled from a mobile device.
**Note – The EnergyBar 832 is for use in North America (USA, Canada, and parts of Mexico) and other locales where the electrical service grid provides 120VAC 60Hz power. In other regions which use 230VAC 50Hz power, APEXel systems are bundled with an EnergyBar 6 equipped with 6 outlets specific to that region (UK,, AU, Universal, or Schuko). EnergyBar 6 models do not include the EB832’s per-outlet power monitoring, 1LINK or DC24 ports, or per-outlet indicator LEDs.
Super Easy Mounting
Both the Apex-EL and the Energy Bar 832 have an innovative attachment system, making them easy to mount and access all connections. A hinged mount allows the controller to be flipped up to make your connections, and flipped back down, tucking them away therefore making it difficult for water to enter via a cable.

Low Maintenance
The Alkatronic automatically monitors the alkalinity (KH) in your tank, as well as corrects any deviations within the user's settled reference intervals by dosing carbonates from its own dosing pump or by activating a Bluetooth Smart Outlet (included).
Calcium Reactor users can benefit from precise control over the CO2 to the Ca reactor through the included Bluetooth Smart Outlet controlled by the Alkatronic. As long as the dKH is below the set value, this outlet will be on and let the calcium reactor be controlled by the pH controller. If the value rises above, it will override the ordinary regulatory equipment and shut off the CO2 until the dKH is back within range.
What is Alkalinity (KH)?
Alkalinity is a means of quantifying the stability of pH in aquarium water. It is a measure of the concentration of various negatively charged ionic compounds (anions) such as carbonates, bicarbonates, borate and hydroxides in the aquarium water. Although a simple and affordable test, user error and time is taken out of the equation so that one can rest assured that their reef aquarium is safe and stable.
Why is Alkalinity Essential?
Alkalinity maintenance is a critical aspect of coral reef aquarium husbandry. If left unchecked, alkalinity can drop below a critical level and pH begins to fluctuate more wildly than the suggested daily pH shift of +/-0.2 for marine aquaria, causing stress to livestock. In a marine aquarium, the desired alkalinity is usually between 7° and 10° dKH (German Carbonate Hardness).
The Alkatronic makes it possible to monitor the buffering capacity and automatically manage KH levels of your aquarium water in a simple all-in-one device.

What is ICP?
Inductive Couple Plasma, or ICP, is an instrument commonly used for testing when complying with the EPA regulations in food and environmental issues. ICP will test your aquarium’s water elements down to the parts per million (ppm), or even parts per billion (ppb), surpassing the accuracy of any hobby level test kits.
How does ICP work?
Salt water is injected into a plasma chamber that is approximately 10,000 degrees Celsius. This extreme temperature breaks everything in the sample apart into the basic elements. Every element is then released at a specific wave length and the machine measures the concentration of the element by how much energy is released at that specific wave length.
Why is ICP testing for your water so important?
Research has shown time after time that certain trace elements are necessary for the growth, reproduction and color of many corals. Knowing exactly what is in your tank’s water will help you troubleshoot issues, see what is missing from the water that may be inhibiting coral growth and coloration, or simply help you make educated adjustments to give your corals the best possible environment to thrive. Is this test only for aquarium water? Certainly not. It is beneficial to test your drinking water to insure that chemicals, metals or other harmful elements are not ingested by your family or pets.

Royal Nature Ammonia Professional Test
$19.00
Ammonia - NH3 can appear in two forms in water
1. Free ammonia
2. Ammonium ion NH4
NH3 + H = NH4
Ammonia is considered as ion with high toxicity and thus is important to make sure that we don’t have high levels of Ammonia in our tank. The NH3/NH4 ions are strongly depending on PH levels. The lower PH is - the more NH4 we get. (NH4 is not as toxic as NH3) in PH of 8.0 - 8.4, NH3 will be dominant.
Royal Ammonia test kit will measure both: NH3 and NH4 levels in your tank.
There are few sources of Ammonia in reef tanks:
1. Tap water.
2. Impurities of supplements like Ca and Mg. when one is trying to use inexpensive and not analytical grade metals like Ca or Mg, the immediate effect will be higher levels of ammonia.
3. Impurities in salt mixes that may use cheaper versions of Ca and Mg or any other supplement with high level of Ammonia.
In sea water NH3/NH4 levels should be below 0.04 mg/l and shouldn’t be detectable by the test
The new Royal Ammonia test kit can be used in fresh/saltwater aquariums and can be determine with a finely tuned color chart which includes a concentration range from 0.01-5 mg/l and up to 100 tests.
Caution:
When doing a water change to bring down high ammonia levels make sure you have tested the PH levels first. At lower PH values loose ammonia in the aquarium will mostly be in the form of NH4+ which is only slightly toxic. A large water change may raise the PH to normal levels of 8.0-8.4. At these PH values most of the remaining NH4+ will convert to highly toxic NH3.
Safety instructions:
1. Keep out of the reach of children.
2. Ammonia reagents can cause severe burns.
3. In case of contact with skin or eyes, rinse thoroughly with fresh water.
In case of accident or illness consult a physician immediately.

Royal Nature pH & kH Professional Test
$16.00
DKH and pH are much related to each other. There are many life forms in the salty tank that absorb carbonates. Calcareous algae are one of them. By a constant consumption, these carbonates that are responsible for our Alkalinity buffering system get depleted which leads immediately to higher acidity causing pH to decline. This critical relationship between pH and DKH must be detected on a regular basis.
By adding Royal Sodium Bicarbonate we make sure to keep our carbonates in the range of 8-10 DKH and in this way keep our pH in the desired level of 8.2-8.4
pH in a saltwater aquarium should be increased very slowly, preferably not more than a 0.1 increase over a 24 hour period.
For that reason, we have developed this powerful tool of Royal pH and DKH professional test kit, giving you the ability to measure DKH and pH in one step. If DKH is measured by you constantly day after day as it should be, then in the same time and no more steps you get also the pH readings with just an extra look into another chart. This test will give you the confidence that the close relationship in your tank between DKH and pH is kept and coral skeletal growth is not interrupted.
pH and KH - 1 Step only Test Instruction
Each kit will give you 150 tests.
1. Using the 5 ml syringe, add 5ml of aquarium water to the test vial.
Attention: before any use of the vial test, make sure it is washed with RO water only and dry it up with a soft paper.
2. Using the 1ml syringe, place the metal needle firmly.
Draw up the dKH/pH solution until the black part of the syringe is at the 1.00 ml mark.
• Before this step, ensure that the metal needle is empty of liquids and that it's submersed in water the entire time to avoid air entering to the syringe.
• The presence of small air bubble between the liquid and the black part of the syringe is normal and will not influence the result.
3. Start adding dKH/pH solution to the test vial.
• Pay attention that during the titration you will observe two color changes: from pink to green and from green to yellow (see the picture below).
• After first drop you will get solution with a pink color that will get darker.
4. Continue adding dKH/pH solution drop by drop into the test vial until the color will change from pink to gray (first point VpH): 
• Swirl a little after each drop.
• The right point is gray color with no pink or green tone (addition of one more drop into the solution should add green tone to gray).
5. Read the position of the black part of syringe for VpH value (each division corresponds to 0.01 ml).
6. Continue adding dKH/pH solution 5-8 drops at the time until the green color of the solution will become brighter, then add drop by drop until you will get the olive color (second point VdKH): 
• Pay attention that the right color is olive and not completely yellow.
7. Read the position of the black part of syringe for VdKH (each division corresponds to 0.01 ml).
(use the two upper lines of the table for alkalinity determination)For alkalinity determination, compare the obtained value of VdKH using the table
• Typical values of alkalinity in the aquarium are in the range of 7-11dKH
For pH determination you will need both VpH and VdKH values.
1. Find the measured VpH value in the left column of the table and the VdKH in the upper line.
2. Find the intersection of a line with the right VpH and the column below the measured VdKH and read the pH value.
• Typical values of pH in the aquarium are in the range of 7.6 and 8.4
Example:
According to the titration the VpH was found to be 0.72ml and VdKH equal to 0.05ml.
In this case the alkalinity in your aquarium is 11.4 and pH equal to 8.43 (see the picture below).
Royal Nature Nitrite Professional Test
$15.00
The Nitrite ion NO2 is created from Ammonia in a process known as nitrification or Nitrogen cycle where bacteria convert Ammonia to Nitrite and then to Nitrate by oxidizing it. This process can take 3-4 weeks.
In sea water the NO2 levels shouldn’t be detectable by this test. Levels of more than 0.05 PPM are dangerous and not acceptable.
The new Royal Nitrite test kit can be used in fresh/saltwater aquariums and can be determine with a finely tuned color chart which includes a concentration range from 0.1-5 mg/l
Royal Nitrite professional test kit is designed to be easy to use and read plus give you 100 tests per kit.
Royal Nature spent the time to make this kit not only affordable, but easier to read and more accurate. The biggest complaint on titration test kits is reading the color shift to be accurate. Since color variation can be a subject to many factors - ambient light, way of sample’s hold. Individual eye color’s reflection - we in Royal Nature wanted to take the time to use analytic studies to make the colors fit the average eye reflection.
The Royal Nature Nitrite Test Kit is a one step process using 1 powder.
The test measures NO2 levels in ranges 0.1, 0.3, 0.5,1, 3, 5.
NITRITE TEST INSTRUCTIONS - 1 step only
Keep out of reach of children.
Attention: Before any use of the vial test or measuring scoop, make sure it is washed with RO water only and dry it up with a soft paper.
Results of Royal nitrite professional test kit are in PPM.
Each kit will give you 100 tests.
1 step only:
1. Using the 5 ml syringe, add 5 ml of aquarium water to the test vial.
2. Add to the test vial - 1 level scoop of NO2 - 1 reagent and swirl gently for 30 seconds.
3. Allow it to stand for 2 minutes.
4. Hold the test vial next to the supplied color chart on a part of the chart which is white and compare the colors looking from the side of the test vial. Read the corresponding nitrite content. An intermediate color corresponds to intermediate nitrite content.
Royal Nature Alkalinity Professional Test
$15.00
Alkalinity can be measured by titration a sample with a strong acid until all the buffering capacity of the aforementioned ions above the pH of bicarbonate or carbonate is consumed. This point is functionally set to pH 4.5.
At this point, all the bases of interest have been reached to the zero level; hence they no longer cause alkalinity.
Alkalinity is typically reported as mg/L as CaCO3.
This can be converted into equivalents (dKH) when one equivalent is equal to 17.848mg/L.
Each test uses a two-part chemical reaction and a syringe. Unlike the Ca and Mg test, here we add the chemical solution to the sea water until the final color is hit. We also guarantee you’ll get 200 tests out of each DKH test.
In Royal Nature Alkalinity test the correlation between end point of titration and value of alkalinity was calculated with a lot of adjustments. Our ability to produce in small batches is critical to achieve analytical calibration which is a key to our tests accuracy.
Each kit will give you 200 tests.
1. Using the 5 ml syringe add 5ml of aquarium water to the test vial.
Attention: before any use of the vial test, make sure it is washed with RO water only and dry it up with a soft paper.
2. Using the 1 ml syringe, place the plastic tip firmly and draw up the Alk-2 until the lower end of syringe's black rubber is right on the 1.00 ml mark.
• Before this step, ensure that the plastic tip is empty of liquids and that it's submersed in water the entire time to avoid air entering to the syringe.
• The presence of a layer of air between the liquid and the black part of syringe is normal and will not affect the result (The normal air layer you should see is equal to 0.1 ml).
3. Start adding Alk-2 to the test vial one drop at a time, swirling a little after each drop. After 2-3 drops you will get solution with blue color: 
4. Continue adding Alk-2 to the test vial until the color will change to: Yellow 
• There will be short stage of green color. The final result is when the solution is changed from green color to yellow. When the solution is green you are very close to the final result - about (1-2 drops).
Pay attention that by adding Alk-2 more than needed the yellow color will get brighter.
5. Note the position of the lower black part of syringe (each division corresponds to 0.01 ml) and obtain the alkalinity result from the table. Readings should be taken at the position of the lower end of syringe's black rubber.
NSW alkalinity is around 7. Our recommendation is to keep DKH levels in the tank between: 7-10.
In case of low alkalinity use Royal Sodium bicarbonate to keep parameters between: 7 – 10.
Royal Nature Magnesium Professional Test
$20.00
Keeping the tests user friendly was a big concern for us and our chemists were able to get the magnesium test to two steps only. Having clear color changes in the titration was also key, to help eliminate user confusion on guessing if they are reading the test accurately.
Each test uses a two-part chemical reaction and a syringe to add water until the final color is hit. We also guarantee you’ll get 50 tests out of each magnesium test.
In theory we are using the same ideas as in Ca test. The chemical solution here is very sensitive to PH and therefore we need to use a strong buffer.
Not as in the Ca test, our challenge here is to precipitate the Ca first and then find Mg levels. Our way of testing Mg is a bit different and based on direct titration where we add sea water to the chemical solution.
A special correlation table where we can correct Mg levels by knowing Ca levels without the need to precipitate it. Our ability to produce in small batches is critical to achieve analytical calibration which is a key to our tests accuracy.
MAGNESIUM TEST INSTRUCTIONS - 2 steps only
Each kit will give you 50 tests.
We recommend doing the Calcium test first.
1. Using the 3 ml syringe add 2 ml of Mg-1 to the test vial.
2. Add one flat 0.15 ml scoop of Mg-2 powder to the test vial and swirl.
• The solution should appear this color: 
3. Using the 1 ml syringe, place the plastic tip firmly and draw up the aquarium water until the lower end of syringe's black rubber is right on the 1.00 ml mark. Before this step, ensure that the plastic tip is empty of liquids and that it's submersed in water the entire time to avoid air entering to the syringe.
• The presence of a layer of air between the liquid and the black part of syringe is normal and will not affect the result. (The normal air layer you should see is equal to 0.1 ml.)
4. Begin adding aquarium water to the test vial one drop at a time, swirling a little after each drop until the solution appears this color: 
Attention: before any use of the vial test, make sure it is washed with RO water only and dry it up with a soft paper.
• If the solution in the test vial does not reach this color and you have used all the aquarium water in the syringe, return back to step 3 (It means that concentration of magnesium is below 970ppm).
• If after adding another 1.00 ml of water a second time, the color is not changed this means the concentration of magnesium is below 360ppm.
Faster test can be achieve without the plastic tip with a potential mistake of 2%.
5. Note the position of the lower black part of syringe (each division corresponds to 0.01 ml) and obtain the magnesium concentration from Table 1. Readings should be taken at the position of the lower end of syringe's black rubber.
• If you needed to return to step 3 a second time then use Table 2 to obtain the magnesium concentration. The normal concentrations for magnesium are between 1280-1540 ppm (salinity related).
The result is accurate when the concentration of calcium is between 350-450ppm. If the concentration of calcium is not in this range then you can correct the result from this table:
NSW Magnesium is around 1350. Our recommendation is to keep Magnesium levels in the tank between: 1290-1450 PPM. In case of low Magnesium use Royal Magnesium Chloride to keep parameters between: 1290-1450 PPM.
