Great forum. New 29,000 gallon concrete pool opened for first time mid April. Found forum a week later after buying tons of tabs and dichlor. How fast can CYA possibly accumulate I think. Should be good with tabs for a couple years. Well, 6 weeks in, using only tabs and dichlor once for shock, CYA already at 30. No conditioner added whatsoever. Will bump up to around 50 and switch to bleach. Weird how pool guy "indoctinating" me to pool never mentioned CYA. It be well over 100 by August and I'd probably be loading up on algecides, etc. from pool store.
Anyway, thanks to the moderators. This is a great forum, I've learned tons. My pool is currently sparkling and I look forward to keeping it that way.
And oh yeah, Go Red Sox!
