After lots of rain and vacuuming to waste then refilling, my CYA is down to 50!!
Last night I vacuumed to waste and cleaned the bottom of the pool, backwashed, then shut the pump off. This AM the pool was crystal clear with nothing at the bottom of pool. After 2 hours of filtering this AM I noticed the brown stuff gathering again. So, I am thinking that the problem is the filter. I am going to add DE this PM or, do you think I should flock?
You people are the best! I don't think in all the years I have owned a pool, my pool has been better balanced and beautiful! Thanks again
