Cloudy Water
Hi all, I've been dealing with a cloudy pool for the past week. It started when I let things go for a few days while being gone. I came home to a mild algae problem. I bumped my FC to almost 20, brushed, backwashed, etc to clear it up. The algae is gone, but the water remains cloudy. Adding to my confusion is the pressure on my system doesn't seem to ever change after I backwash and the backwash is rather dirty.
My numbers right now are
FC 7.0
CC 0.0
PH 7.4
TA 125
CH 200
CYA 40
I have a sand filter. I've tried adding 1/3 cup of DE through the skimmer. I got the resulting 1 lb increase in pressure, but nothing else changed. I'm hoping I'm missing something obvious.
25k gal pool, 18 x 36, 3' to 8' depth. Vinyl lined. Single speed pump
