Dave,
The water looks fantastic, it has been several days since I added any bleach so I believe the cya is certainly starting to work. I agree that the pucks have been super slow, but they are doing their job. I will continue to let the pucks run until I am out, it seems as though it will be several weeks before any swimming occurs around here. I think by then the cya will be up to a reasonable level and I will switch to bleach.
