Just tested my water. I have an FC level of 4 and a CYA level of 45/50. Pool is very clear. SWG is currently operating at 40%. Ph is 7.6. Is my CYA level good? I tried reading the chart on the site, but wanted an experts opinion.
If you raise your CYA, you may be able to lower the SWG setting which will help extend the life of the SWG cell. 80 ppm is usually recommended for SWGs because of this reason.
