I posted a while back about what I thought was pollen in the pool. I am having to vacuum to waste nearly every week to keep it away which is **** on chemicals and water bill. This didn't start happening till a month ago, never had this problem last year except once. It looks like a brownish/yellow dust that evenly coats the whole pool bottom. If you leave it for a while it accumulates in seams and around the edged of the bottom of the deep end. I've tried repeated brushing, it just clouds up then re-settles. Filter socks make it about 2 days before they are clogged. I added DE to bump up 2 (13) PSI, after brushing once the pressure climbed another 5-6 (18) PSI then the following day dropped back to 15 PSI. I let it go and my floor was covered again a week later. 10 minutes ago I just vacuumed to waste. put in 6 cups of DE and filter socks.
CYA 50 (i'm bringing it up)
Borates probably 30 after the dilution
OCLT .5ppm (once it was 1 but repeated with deeper sample and it was .5) never greater than 1
I believe I do have a small suction side leak as I occasionally get bubbles from the 1st 2 returns but that has been for months and I don't seem to have a water leak.
So... is it crazy pollen season and I'm screwed, is my filter shot (sand is 2 years old), or what. I am about to buy the "enzyme treatment" the pool store wants to sell me, I'm that desperate. Any ideas???
