Help my pool water is possessed!
I have add the recommended start up dose of CYA but it still measures 0. FC will drop from 7 to 0 in 1 day. PH keeps rising also.
No water loss. For past 6 years the PH has not needed any adjusting and CYA has never been an issue since going BBB. Water stays clear but not sparkley.
I live in N TX so the temp has been holding at about 105 for an air temp. I have several trees so even though the pool gets a lot of afternoon sun it is about 40-60% shaded all day. I use Clorox. Added a gal of acid to balance PH then shocked the pool to FC24, held overnight but still no CYA after adding 10lbs and PH is rising again plus using clorox fast.
Thanks
