Put 3 lbs. wallyworld (Aquachem) CYA in yesterday via sock hung from ladder. Almost all disolved in 24 hours (may have 2 oz. still in sock) and my Ph went from approx 7.7 to 7.2/7.1 in that time. Is this kind of drop normal/expected?
Don't think it's a problem.....just surprised how fast it disolved and the swing on Ph that wide.
As always, thanks for all the help!!
