The JBL ProAqua Test Ca Calcium was designedfor the simple and reliable monitoring of the aquarium water values. Determines the optimal calcium value for vigorous and healthy coral growth (Recommended level in saltwater: 400-440 mg/l calcium).
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 natural calcium level of the sea is 390–440 mg/l. 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. For this reason adding calcium compounds without hydrogen carbonate (such as calcium chloride), is pointless. A calcium level of 400–480 mg/l is proved to be ideal for marine aquariums.
+ 1 drop measuring solution 3 = 20 mg/l calcium
+ colour change from pink to blue
+ includes syringe to measure amount of water
