dosing question

[Dan49]

My question is , should be adding kalk to my system, I am now using Bi-onic 2 part and just started vinegar last week . I have a mixture of sps zoas a couple of soft corals. The tank looks good and water tested good also. I wanted to know if the kalk is needed for further coral growth thanks ,Dan

Kalk is a cheap alternative to dosing 2 part. Kalk will have a balanced amount of calcium and alkalinity in it. Further dosing of 2 part to keep your parameters in spec may be required.
