I have brightwell aquatics reef code a&b calcium and alkalinity additive. No matter which one I dose with I get some "snow". I have been reading some on the issue but still not sure what's going on. My calcium is in the low 300s and I lost the color card for alkalinity test. All other parameters are good. What is the cause, and how do I get this to stop and my calcium up? I have a frogspawn, hammer, duncan, birdsnest, and gonoporia. I need calcium levels up, but last 2 times I have dosed I had a snow storm.
