Aquavitro Shrimp GH is a solution that adds a complete spectrum of minerals to shrimp aquariums. Shrimp GH takes into consideration both the mineral requirements of shrimp and the mineral content of their natural waters for the purpose of creating an optimal shrimp environment. This treatment adds calcium, potassium, iron, and 6 trace minerals all in the correct biological ratio for shrimp. This blend helps encourage healthy molting and works to prevent death due to lack of calcium and other causes of poor molting. Comes in a 150 ml bottle.
