Recommended CYA level?

[skyjenn]

I am just learning about BBB...I am starting to understand the long term effects, but have a question about cya staying high. I live in a High Rain area, therefore, ph is lowered on a regular basis and backwashing water replacement common. I have always been told not to let the cya zero out. Now that I am researching BBB, is there a cya recommended level? We have rain every day this time of year, sometimes twice a day.

Welcome to TFP!

For regular pools, we recommend a CYA of 30 to 50 ppm. For saltwater pools, we recommend a CYA of 60 to 80 ppm.

If you have a lot of water replacement, you'd be one of the fortunate few who can use trichlor pucks with careless abandon. Well, almost. Still, play with the pool calculator and see. Crunch some numbers, see what works out cheapest.
