AquaHomeTest Ca+Mg: Calcium+Magnesium | Combi-Test for seawater-aquarium
Ca 300 - 498 mg/l (ppm)
Mg 820 - 1800 mg/l (ppm)
About calcium and magnesium:
Along with sodium, potassium, chloride and sulphate, calcium (Ca2+) and mag- nesium (Mg2+) are two key components of natural seawater. Magnesium and,
above all, calcium are important growth factors for organisms which form calcareous skeletons, such as hard coral and coralline algae - both elements form the basic substance of the calcareous skeleton. Furthermore, magnesium and calcium are involved in numerous biochemical processes. In saltwater applications, the reduction in the magnesium or calcium concentration caused partly by cellular metabolism and partly by skeleton formation means it is necessary to test the concentration levels on a regular basis and, if required, add more of one or both ions. This makes it possible to guarantee
optimum, near-natural living conditions for all organisms and to prevent longterm damage. In natural seawater, the calcium concentration is 400 - 410 mg/l (ppm) and the magnesium concentration is 1280-1320 mg/l (ppm). They also have
a fixed ratio of 1: 3.25 to one another. Due to the chemical and biochemical interdependencies between calcium and magnesium, you should also aim to achieve this concentration ratio in saltwater tanks.
The calcium concentration is determined first, and then the magnesium concentration is determined using the same sample. To avoid cross-contamination, the dosing syringes with the proper tips must only be used again for the same reagents!
Shelf life and storage: 6 months after opening.
Store in a cool, dark place.

The Fauna Marin Phosphate Test is very high-resolution and can determine the phosphate concentration with a particularly high accuracy in the low concentration range between 0.01 and 1 mg/l with clear color recognition.
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.

AquaHomeTest K: Potassium-Test for seawater-aquarium
300 - 500 mg/l (ppm)
Potassium is a vitally important macronutrient for all living beings. In natural
ocean water, this alkali metal is present in an average concentration of 408 mg/l.
In a saltwater aquarium, the potassium concentration is usually kept stable by
regularly changing the water. Nevertheless, a lack of potassium can occur
in individual aquariums tanks due to the use of zeolites and other adsorbents.
One sign of a possible lack of potassium is clear discolouration of corals and
retraction of polyps. The potassium level in a saltwater aquarium should be
checked regularly to ensure that the level is between 380 and 420 mg/l.
Information regarding the potassium test
:The precision of the measurement
results may be increased by determining
a „correction value“.
For this purpose a measurement
with reagent “Standard”
(potassium) is carried out.
This measurement indicates the correction
value that should be included during
each potassium measurement.
We recommend determining the
correction value again every 3- 4 weeks.
If phosphate is present in too high a concentration there may be an increase in growth of undesirable algae and if the phosphate level is higher than 0.04 mg/L the growth rate of corals and calcareous algae may decrease by as much as 90%.
Washing fish food (a rich source of phosphates) after thawing can significantly reduce the input of phosphate, and using a high grade, phosphate free activated carbon can also help to keep phosphate levels as low as possible.
The Salifert Phosphate test kit detects, in less than 5 seconds, the level of phosphate present.
There are two different ranges within the kit: a low range for phosphate-phosphor from 0.01 - 1 mg/L and a medium range for phosphate-phosphor from 0.02 - 2 mg/L.
Sufficient for 60 tests.
Can be used for marine, fresh and garden pond water.
INSTRUCTIONS for usage
The phosphate values are in ppm phosphate. If you prefer a reading in ppm Phosphate-Phosphor then divide the reading by 3.
HIGHER SENSITIVITY Should you require an even higher sensitivity then double the water sample and the reagents. The scale should be then divided by 2.
Calcium is a major constituent of coralline algae, the skeletal material of hard corals and the skeletal needles of soft/leather corals. In many cases too low a calcium concentration retards coral and coralline algae growth.
Calcium also fulfills many important biological functions.
In a healthy aquarium, the growth and multiplication of corals, calcareous algae and other organisms can result in calcium depletion. To maintain a stable environment it is important that the calcium content should not fluctuate by more than 15 mg/L from the optimum range of 420 - 450 mg/L so regular testing should be carried out.
This means that any calcium test used should have an accuracy of significantly less than 15mg/L otherwise it will be difficult to monitor such fluctuations.
The Salifert test kit measures in steps of 5 mg/L and has an accuracy of 10 mg/L.
The color change is precise, detecting small but significant fluctuations in the concentration of calcium.
The test is not affected by magnesium.
Sufficient for 50-100 tests.
Can be used for marine water, freshwater and garden pond water
Ca-1 reagent contains sodium hydroxide and is strongly irritating to skin and eyes. In case of contact with skin wash with plenty of water. In case of contact with the eyes wash with plenty water and consult a physician immediately.
Not for consumption. Keep out of reach of children. If swallowed contact a physician immediately.
INSTRUCTIONS for usage.
Natural seawater contains 400 - 425 ppm calcium.
The unique design of the Coralife Deep Six Hydrometer allows hobbyists to take water samples at six inches in depth without submerging their hands in the water, thus avoiding the possibility of contamination. Samples taken at six inches in depth have been proven to result in a more accurate salinity reading than surface samples.
Every unit is calibrated, tested and certified for accuracy. Each Deep Six Hydrometer is then assigned its own individual certification number.
