When there are insufficient areas of a tank which are deprived of oxygen (anaerobic zones) or denitrification is not taking place properly, nitrate will build up. This can also happen in an aquarium where the biological loading on the system is causing an imbalance e.g. if there is excessive livestock for the aquarium volume or over feeding is occurring.
The build up of nitrate can result in unwanted algae growth and the slowing down of coral growth.
The nitrate concentration in a reef aquarium should be lower than 1 mg/L, although fish only aquariums would usually have a higher concentration.
Just as with nitrite, many nitrate test kits are prone to amine interference which can make the levels of nitrate appear much lower than they actually are.
The Salifert test kit does not suffer from such interference and gives accurate and quick results with a total testing time of less than 3 minutes.
The test kit range goes from a very low to a very high nitrate concentration (approx. 0.2 - 100 mg/L as total nitrate).
Sufficient for 50 tests.
This test offers two ranges:
Clean test vial and scoop after use. Store this kit in a dry place.
KEEP OUT OF REACH OF CHILDREN.
Procedures for both ranges:
Place the test vial on the white part of the colour chart and compare colours looking from the TOP.
Use diffuse daylight when comparing colours.
If the colour corresponds to a lower value than 10 mg/L nitrate then it might be beter to compare colours as shown for the low range (see below).
If the medium range colour comparison procedure gave a reading lower than 10mg/L then you can use the low range procedure. This will increase the accuracy.
The colour for the low range procedure has to be compared by looking through the SIDE of the test vial.
The white part of the colour has to be held firmly against the opposite side of the test vial. Use diffuse daylight when comparing colours.
The colour is, by looking through the side, amplified by approximately 10 fold. For this reason you have to divide the colour chart values by 10. For example 2 will become 0.2 and50 will become 50.
Seachem Reef Reactor Lg
Reef Reactor™ is a high-purity source of aragonite, which supplies all important elements for optimal ionic balance and robust coral growth and coloration in reef aquaria. It has a grain size of approximately 1-3 cm. (Reef Reactor™ Md is 0.5 - 1 cm). It is intended for use in calcium reactors where it is dissolved slowly with the addition of CO2. As it dissolves, it provides calcium, magnesium, strontium, potassium, and carbonates among other important elements for reef aquaria. It is excellent at increasing and stabilizing alkalinity, which also supports a stable pH and encourages the rapid formation of coral skeletal material. With high levels of both calcium and magnesium, it offers an excellent means of balanced supplementation for rapid growth and propagation of corals and calcareous animals in reef aquaria. It possesses the highest level of soluble potassium of all competing brands while exhibiting the lowest levels of both aluminum and phosphorus.
Rinse Reef Reactor™ prior to initial placement in your calcium reactor. The rate of water flow through the reactor in conjunction with the pH of the water inside the reactor will control the rate of media dissolution. Follow the manufacturer’s instructions furnished with the calcium reactor and adjust the rates of water flow and CO2 injection to attain the desired concentrations of calcium and alkalinity in the effluent.
Use Seachem’s Reef Status™: Magnesium and Reef Status™: Calcium test kits to measure alkalinity, calcium, and magnesium concentrations.
