That makes sense, but I have a follow-up question. Once I reach the ppm I want to be at w/ the CYA, do I have to stop using the dichlor so that my CYA won't go any higher? If so, what eventually makes the CYA come down so that I can use more of that? Just don't want to buy that much dichlor and not be able to use it once my CYA is at a proper level.
