CC=0 - .5
CYA=less than 20
He's adding more CYA today.
Short story - Water is cloudy after a swimmer got in. Can see bottom but whitish cloudy.
Long story - I helped him open his pool this year. It was completely drained when I got there. He sprayed the inside of the pool with straight bleach and brushed with a wire brush to rid the pool of what appeared to be black algae from last year. Resprayed straight bleach after brushing, twice. Filled the pool, brought the pool to shock level with CalHypo (he got a little carried away as evidenced by the CH number) and held it there until we passed the OCLT. Pool came down quickly off shock level, which was no surprise given it's in Texas with zero CYA (at the time) but a little surprising given I hooked up my now unused Liquidator to his pool and filled it with bleach. He added enough stabilizer to bring it up to 20, adding more today (I know, that's repetitive), but his concern was the cloudiness after a swimmer got in. I told him today that the bottom of the pool was full of silt and such and that it would take a while for the pool to clear. I think they just stirred up the fine silt sitting on the bottom and sides.
This is an 11,000 gallon DiamondBrite pool, cartridge filter. Brand new carts, just rebuilt the filter housing, and of course we installed the LQ.
He is using a TF-100 to test.
