I am using BROMINE, not dichlor etc. My stabilizer level does read 'low'.... SO DON'T MESS WITH IT? And yes, I keep it covered. Its just that I was hoping that it would help with water clarity and an increasing amount of 'foam'... I guess I don't understand because all the other levels (total bromine, Alkalitiy, Ph. etc are all within range. I just don't want to 'keep adding chemicals' (like water clarifier, de-foamer etc.
