Employing an easy-to-read color chart for quick comparisons, it can test for ammonia levels from 0 to 8 parts per million.

Liquid testing ensures a completely accurate readout every time you use this test kit from API. Designed specifically to test for ammonia, the most harmful chemical for aquariums and a leading cause of fish death, it’s a streamlined product that may well be the best aquarium test kit for the money. In short, the API Master Test Kit is our go-to kit for freshwater aquariums, and we give it our strongest recommendation.įrom the same company that produces the industry-standard test kit for freshwater aquariums, the API Ammonia Freshwater & Saltwater Aquarium Test Kit is a versatile and inexpensive solution to testing for every fish tank.

Simply fill the test tubes with water from your aquarium, add the test drops to individual tubes, and compare the color to the included reference card. Whether you’re buying a test kit for your first freshwater aquarium or your fiftieth, API Master Test Kit is a fine choice.ĭesigned not just to measure the six essential aquarium levels-ammonia, pH, high range pH, water hardness, nitrite, and nitrate-but also to adjust them when necessary, API’s test kit is an all-in-one solution to keeping your fish tank healthy and looking its best.Įquipped with four test tubes, a holding tray, a test tube rack, and a laminated color card, testing your aquarium levels is fast and easy.

You can oder the complete test kit with coloure chart and test accessories or only the reagents at the refill kit.Many aquarists consider API’s Freshwater Aquarium Master Test Kit to be the gold standard for at-home testing, and with good reason. + includes syringe to measure amount of water + one drop of Ca reagent 3 = 20 mg/l calcium + one drop of Mg reagent 2 = 100 mg/l magnesium In the marine aquarium a magnesium content of 1200 to 1400 mg/l has proven to be ideal. The natural magnesium content in the sea is approx. In addition to calcium, magnesium in sufficient quantities and in the right proportion to calcium is required for the optimal skeletal and shell structure of these organisms. A calcium level of 400-480 mg/l has proved to be ideal for marine aquariums.

For this reason adding calcium compounds without hydrogen carbonate (such as calcium chloride), is pointless. In order for the organism to make the best use of the calcium, the correct ratio of hydrogen carbonate must also be present in the water. The natural calcium level of the sea is 390-440 mg/l. Why test? Invertebrates (stony corals and soft corals, sponges, sea urchins, crustaceans, mussels, snails etc.) and the popular red coralline algae found in marine water require sufficient levels of calcium for healthy growth. The magnesium content can be calculated by subtracting the calcium content from the total value of Mg + Ca. As the magnesium content can only be measured by recording the sum of magnesium plus calcium, the two tests have been combined in one pack. The JBL ProAqua Test MgCa Magnesium/Calcium is an easy to use drop test to measure the magnesium and calcium content of saltwater.
