So I bought my granular CYA,poured it in a sock( all 3lbs) and have it dangling in front of the jet near the stairs. How long should I let it hang for. It seems from other posts that it will take forever to dissolve right? My CYA was at 0-20. Would removing it after 24hrs be ok and then testing in another 24 hrs? I will let the sock soak in a pail of pool water until I think I need it again.
