I am a new (well new since I was a kid) pool owner and I've been lurking and reading this forum for quite some time as a guest. Now that I have a pool coming in I've been brushing up on pool chemistry/ (I have a minor in chemistry that I've never used, so this pool testing is quite fun to me)
Anyways - the fun is this...who wants to guess what my brothers (coming over for mothers day and bringing water) 10 year old pool water CYA will be?
He's always used a auto inline feeder with the tri-chlor pucks and keeps mentioning to me how clear and how much chlorine he uses for his pool.
I guess it must be possible to keep a pool with CYA that my guess is will be off the charts clear and safe, but I am baffled. OH well...can't wait to test later on this afternoon. Only issue is I am torn to tell him the bad news as he is SO HAPPY with is pool clarity, etc.
What would you all do ?
