Nitrite (NO2–\u003cspan\u003e), which is highly toxic to freshwater species in particular, is produced in the first stage of the bacterial process. If the nitrification process works, nitrite is converted to the comparatively non-toxic nitrate in the second stage.

An algal bloom is often the result of a high nitrate level in an aquarium. Some reef aquariums have ultra-low nutrient conditions – nitrate shortages can occur in cases such as these. Therefore, the nitrate concentration in the aquarium water should be tested regularly. It is advisable to keep the nitrate concentration in freshwater aquariums below 50 mg\/l (ppm), whereas the concentration should not exceed 20 mg\/l (ppm) in saltwater applications. When nurturing hard coral, the aim is to keep the nitrate concentration below 10 mg\/l (ppm). \u003cspan\u003eLower limits for nitrate depend on the general conditions in the aquarium.\u003cbr\u003e\u003c\/span\u003e\u003cbr\u003eWith the high resolution Tropic Marin® Nitrite\/Nitrate-Test Professional\u003cspan\u003e the nitrite and nitrate concentrations can be determined with a particularly high accuracy in the low concentration range between 0 and 1 ppm for nitrite and between 0 – 20 ppm for nitrate.\u003cbr\u003e\u003c\/span\u003e\u003cbr\u003e\u003cdiv\u003eBenefits:\u003cbr\u003e\u003cbr\u003e\n\u003c\/div\u003e\u003cspan\u003e\u003cspan\u003e• \u003cspan\u003eMeasurement range: NO2 0 – 1,0 mg\/l (ppm)\u003cbr\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan\u003e• \u003cspan\u003eMeasurement range: NO3 0 – 20 mg\/l (ppm)\u003cbr\u003e\u003c\/span\u003e\u003c\/span\u003e• Accuracy: NO2 0.002 mg\/l\u003cspan\u003e•\u003cspan\u003eAccuracy: NO3 0.05 mg\/l\u003cbr\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan\u003e• For determining the nitrite\/nitrate concentration in aquaria\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003e• Incl. comparator and phosphate standard to check function and shelf life of the test reagents\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003e• \u003cspan\u003eSufficient for approximately 50 applications\u003cbr\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cdiv\u003eHow to use:\u003cbr\u003e\u003cbr\u003e\n\u003c\/div\u003e\u003cspan\u003eDetermining the nitrite level:\u003cbr\u003e\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003e\u003cspan\u003e1.Shake the bottles before use!\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003e2.Rinse out the glass cuvette with tap water and then several times with aquarium water.\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003e3.Fill the glass cuvette with exactly 15 ml of aquarium water using the dosing syringe and place it in the comparator which serves as a cuvette stand.\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003e4.\u003cspan\u003ePlace the dropper tip on the 1 ml dosing syringe, add 1 ml test reagent A, close the glass cuvette using the stopper, briefly shake the solution and place it back in the comparator.\u003cbr\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan\u003e\u003cspan\u003e5.Then add 4 drops of test reagent C, close the glass cuvette once again, shake it briefly and place it back in the comparator.\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003e6.\u003cspan\u003eAfter 3 minutes of development time, place the glass cuvette in the comparator on the white circles of the nitrite colour card in such a way that the second free opening on the comparator (without cuvette) is underneath the colour card (not on the colour fields) and the narrow end face of the comparator is facing the colour fields.

Phosphates are released into the aquarium water via food and the decomposition process of organic matter. However, an unregulated increase in the phosphate concentration creates problems, such as significant algae growth. In addition, phosphates in salt water aquariums can seriously inhibit the deposition of calcium carbonate in the skeleton formation process of hard corals and, in turn, for their growth. On the other hand, there can be a shortage of phosphate if there is a high stock of plants and \/ or corals and a low fish population. In this situation, phosphate will need to be added. Some reef aquariums are intentionally set up to have ultra-low nutrient conditions – phosphate shortages can occur in cases such as these.\u003cbr\u003e\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eThe phosphate concentration in natural saltwater is approximately 0.06 mg\/l (ppm). However, the phosphate concentration in coral reefs may be much lower, typically between 0.01 and 0.02 mg\/l (ppm). The objective is to establish an appropriate level in relation to the number and type of aquarium inhabitants. In freshwater applications, a phosphate concentration of up to 0.4 mg\/l (ppm) is suitable; however 1 mg\/l (ppm) should not be exceeded. Even a concentration of 0.02 mg\/l (ppm) is adequate for supplying aquatic plants with nutrients.

Phosphates are released into the aquarium water via food and the decomposition process of organic matter. However, an unregulated increase in the phosphate concentration creates problems, such as significant algae growth. In addition, phosphates in salt water aquariums can seriously inhibit the deposition of calcium carbonate in the skeleton formation process of hard corals and, in turn, for their growth. On the other hand, there can be a shortage of phosphate if there is a high stock of plants and \/ or corals and a low fish population. In this situation, phosphate will need to be added.\u003cbr\u003e\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eIn freshwater applications, a phosphate concentration of up to 0.4 mg\/l (ppm) is suitable, however 1 mg\/l (ppm) should not be exceeded. Even a concentration of 0.02 mg\/l (ppm) is adequate for supplying aquatic plants with nutrients. The phosphate concentration in natural saltwater is approximately 0.06 mg\/l (ppm). However, the phosphate concentration in coral reefs may be much lower, typically between 0,01 and 0.02 mg\/l (ppm). The objective is to establish an appropriate level in relation to the number and type of aquariumin habitants. Therefore, the phosphate concentration in the aquarium water should be tested regularly.\u003cbr\u003e\u003c\/span\u003e\u003cbr\u003e\u003cdiv\u003ePackage contents \u003c\/div\u003e\u003cdiv\u003e\u003cul\u003e\n\u003cli\u003e18 ml \/ 0.60 fl.oz. of reagent A\u003c\/li\u003e\n\u003cli\u003e8 ml \/ 0.27 fl.oz. of reagent B\u003c\/li\u003e\n\u003cli\u003e2 glass cuvettes 10 ml\u003c\/li\u003e\n\u003cli\u003e1 dosing syringe 5 ml\u003c\/li\u003e\n\u003cli\u003e1 colour card\u003c\/li\u003e\n\u003cli\u003e1 comparator\u003c\/li\u003e\n\u003cli\u003e1 instructions for use\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e\u003cdiv\u003eInstructions for use\u003c\/div\u003e\u003cdiv\u003e\n\u003col\u003e\n\u003cli\u003eShake the dropper bottles before use!
