With the amount of rain we get during the season, requiring pumping out excess water, I usually have to add CYA several times a season. Adding dry CYA is somewhat of a pain, requiring running the pump longer than usual.

I got to thinking, to make adjustments easier, what if I put granular CYA in empty bleach bottles (well rinsed out) then fill them with water. I imagine it would dissolve by a week’s time (shaken occasionally)? I could make up several bottles of this to keep on hand for easy/quick adjustments. Each bottle could contain enough CYA to boost levels by 10ppm (about 1.75lbs dry CYA for our pool).

Does this sound like it would work well, or is my thinking whacked?
