I started to open my pool about 3 weeks ago. A few minutes after I started the pump, I noticed a huge crack in the filter casing. Could that have sent DE into the pool? The pool was a swamp at that point so I could not tell at the time.
Since then, I replaced the filter. I have been Slamming the pool for about 2 weeks now. It is blue but very cloudy. When I try brushing, I get clouds of brown coming up from the bottom. I just tried vacuuming and the pump basket was full of brown water. Is this DE?
CYA: 30 (assumed, added CYA a few days ago)
I haven't tried the OCLT because it is still cloudy. We just got several inches of rain from the remnants of Bonnie which doesn't help matters.
