One warning if using CaCl2, the chemical reaction with water is quite strong and generates heat. Add the CaCl2 to water, do not add add water to CaCl2; and do not be surprised if the glass you are mixing it in becomes warm. I would not add CaCl2 directly into my tank for fear the fish might try to eat the crystals before they dissolved. |
Thanks. The Chloride is what I was wondering about. I've been told by several not to use it because of too much chloride.
I also did order some CaSO3/4 dont remeber which from Aquariumfertilizer.com also. I will be using it in my shrimp nanao tank as a form of calcium for the shrimp and snails
