The last few years, I've chlorinated my pool with bleach and ran a CYA level around 75 due to the fact the I live in sunny Phoenix, AZ.
However, in the summer months I still have a problem: Every night, I put in the bleach after sunset. Because of the high CYA level, I have to put in A LOT of bleach to get the FC level up to the recommended value. BUT, despite the high CYA level, it is so sunny and hot here that by the next evening my FC is darn near zero again.
Next month I am having my water treated with reverse osmosis to remove calcium. This will remove the CYA, too. Therefore, I am contemplating going with a near zero level of CYA. This will allow me to raise the FC level every evening with a much lower amount of bleach. And, since the FC level will be near zero the next evening with or without CYA, I'll be able to get by with adding much less bleach.
Anyone tried this?
