So ... after spending a few hundred $$ at Lesli's and getting Terrible advice on my green pool (hey, lets put lots of conditioner in ...) I now find my pool with a CYA of 140 (tested by Lesli's this am), cloudy, and the need to lower it asap. It's been properly shocked and the color looks good, there is a small amount of FC but lots of TC. After reading a lot of threads on this board I believe that my only solution is to drain 50%+ of the water.
I have a 29k gal fiberglass in ground pool, is there any risk of me draining too much water out at a time? Any risk to harming the pool? It's July here in Norcal I believe the ground water level is lower than 10 ft. I think so that is ...
One possible strategy would be to pull water from the deep end filter (through the Sta-rite tx-135 filter while keeping the skimmer inlet closed), drain it from the hose outlet on the filter - while adding water to the shallow end. Oh, one other question - when the CYA number is lowered, will the bound Chlorine unbind in the remaining water? Now sure how this works chemically.
Just thinking, not sure on the best strategy here. I just ordering the TF-100 test kit to be delivered mid-this week.
Any thoughts here would be great! Thanks!
