This is our third year needing to SLAM the pool. Each time we have opened, pool has zero chlorine and likely 0 CYA (black dot doesnt disappear when testing for CYA). I put the CYA granulars in a sock in the skimmer and it typically takes days to dissolve. I know that CYA needs to be 30-40 to keep from wasting the chlorine. Is it proper to wait for the CYA to get where it needs to be, or given that this pool needs lots of chlorine anyway in the SLAM process, is it okay and not wasteful to go ahead and start getting my chlorine in there?
Many thanks.
