    Dissolve 2 lbs granular CYA in 1 hour?

    Too good to be true? Normally I add approx 2 lbs at a time in a sock in my skimmer. This time around, I switched to a different brand (Aquabrite Chlor-Sta) and hung the sock in front of my return. This brand is perhaps slightly more granular, but not by much. There was a white fog trailing out from the sock like a comet's tail, and it didn't take long at all...1 hour later it is mostly gone. In front of the return, there is a lot more turbulence and the sock gets buffeted around a lot more. The sock is not compromised in any way, no undissolved granules escaped as far as I could tell. Typically I see it dissolved in the skimmer after 24 - 48 hours.

    I have also noticed that it dissolves much quicker with warmer water temperatures.

    Cool, I'll verify it with the turbidity test tomorrow. My water temp is 86 F. I'm trying to recover from a catastrophic loss of CYA, and this will surely make things easier.
