Product Description
Calcium is a major constituent of calcareous algae, skeletal material of hard corals and the skeletal needles of soft/leather corals. Calcium also fulfills many biological functions.Quite often a too low calcium concentration retards coral and calcareous algae growth.NSW contains 400 – 450 mg/L calcium. Which is also the value we should strive for. For a stable aquarium environment the fluctuation in calcium content should preferably not more than approx. 15 mg/L. This automatically means that the calcium test should be able to monitor comparable fluctuations.Conclusion:In a healthy aquarium growth and multiplication of corals, desired calcareous algae and other organisms results in calcium depletion. Because of the importance of calcium timely corrective measures would have to be taken. For that purpose a proper calcium additive together with an accurate test kit are required.Our calcium testis capable in resolving the calcium content in 10 mg/L steps. The color change is sharp and facilitates the detection of small but highly significant fluctuations in the calcium concentration. Salifert is the only one in offering a true accuracy and precision as claimed.The kit can perform approx. 50 - 100 measurements.Salifert's Coral Calcium additive is manufactured using a very special procedure. This results in a highly concentrated additive that not only makes calcium addition easy, it also avoids that the ionic balance is disturbed when used in combination with our KH + pH Buffer or any other sodium based buffer. Common additives, which contain only calcium chloride or improperly use of kalkwasser (calcium hydroxide), can upset the ionic balance resulting in aquarium water very different from NSW.
Product Description
Calcium alone cannot form the skeletal material of corals and allow calcareous algae to grow. Some other substances are needed as well. A few other constituents are carbonate and bicarbonate. These two substances also have a major impact on the stabilization of the pH in the proper range of 8.1 – 8.4. Such stabilization is also called buffering.
The total carbonate and bicarbonate concentration is also called carbonate alkalinity or carbonate hardness. The only difference between alkalinity and carbonate hardness is a conversion factor.
NSW has an alkalinity of approx. 2.7 meq/L or approx. 7.5 dKH when expressed as carbonate hardness.
For a stable system the alkalinity or carbonate hardness should have a value similar to NSW or slightly higher and should preferably not fluctuate by more than 5%. This means a maximum fluctuation of 0.14 meq/L or 0.4 dKH.
Therefore an alkalinity test kit should be capable in measuring in steps smaller than 0.14 meq/L.
Conclusion:
Since the major buffer components used for coral and calcareous algae growth are bicarbonate and carbonate, they should be added to correct any decrease in alkalinity or carbonate hardness.
A proper formulated buffer should function in such a way that the corrective measures results in a long lasting effect and should not upset the pH of the system. The alkalinity or carbonate hardness should be kept as stable as possible requiring highly sensitive and accurate means for testing.
The Salifert KH/Alk test is very straightforward. It measures in sufficient small steps of 0.1 meq/L or 0.3 dKH with a sharp color change. This makes detection of important yet small change possible.
The kit can perform approx. 100 - 200 measurements.

The HI702-25 are high-quality reagents that are pre-measured, allowing users to achieve fast and accurate measurements with their Copper High-Range Checker® HC. These reagents follow the Bicinchoninate Method in which the reaction between copper and the reagent causes a purple tint in the sample. By simply adding the packet of HI702-25 reagent to the sample, the reaction will take place and the HI702 will determine the concentration from the color that is produced. The results will be displayed in ppm of copper. These reagents are designed to be used with samples that have an expected range of 0.00 to 5.00 ppm copper.

Product description
Nitrite is produced in the aquarium in the forms of fish waste, uneaten food, and by nitrifying bacteria in your aquarium’s natural cycle as it breaks down ammonia. Low levels of nitrite inhibit respiration and suppress the immune system, while high levels cause suffocation in fish. The API® NITRITE TEST KIT reads nitrite levels quickly and accurately in your tank, and tests parameters from 0 to 5 ppm.
Test Kit provides easy, accurate test solutions to measure nitrite in your aquarium:

130 Tests
Test Ammonia Levels in both saltwater and freshwater
Scientifically accurate for professional results
Measures ammonia to help prevent fish loss
Benefits:Ammonia levels in fresh and saltwater aquariums
Follow API Easy Care Guide and use the AMMONIA TEST KIT:
During Regular Care
When addressing Water Problem Solving issues
Taking a few minutes each week to maintain and monitor aquarium conditions is the key to a healthy aquarium. Tropical fish continually release ammonia into the aquarium through their gills, urine and solid waste. Uneaten food and decaying organic matter also add ammonia to the water. Even small amounts of ammonia stress fish; large amounts of ammonia will kill fish. Ammonia is the number one killer of tropical fish. The API AMMONIA TEST KIT is mercury-free, salicylate test for fresh and saltwater fish. The AMMONIA TEST KIT tests ammonia levels from 0 to 8 ppm.
