I have a question about the powder/granules in the sock method, as that is how I do it. Are you saying that if I add via the sock method and then remove the sock, the cya may continue to rise even though I removed the sock?
Say I put the sock in for 4 days then removed it, I would think all cya would be in solution, or are there small undissolved cya in the pool/filter that will continue to dissolve?
I also use a Dolphin with 2 micron robot very frequently - would this remove any small undissolved cya particles ( small enough to get out of the sock but not past the 2 micron filter. I would also think any small particles that got into the robot would dissolve quickly as the flow thru the robot is high.
