I would have posted in the other guy's de into sand filter thread but I think i remember this forum being one that likes new threads for different situations and mine's a bit different than his
SWG didn't work this year and have been doing bleach, forgot for a couple days and it got green.
It's about a week since I killed it all off by shocking with bleach but the sand filter just isnt picking up the dead algae the flow never slows on it by feel (the psi guage on it is worthless.) it's way hazy, can barely see the legs of the ladder on the floor of this 48" pool.
I've read on here about people adding DE to a sand filter to help with this, also by googling I saw some saying they used cellulose fiber.
I saw this at the store yesterday, was cheaper and says it's safer and easier than DE so I got it.
I've been adding between 1-3 cups at a a time and it slows the flow within 2-3 hours so much that I backwash and add more.
I think it's doing something, i mean it doesn't immediately slow the flow when added so I think the flow is slowed later by it catching stuff. But I've backwashed, added cf about 6x since I got it yesterday and not really seeing any clearing up yet.
Is my filter (a 14" intex) so small that it just can't handle catching that much stuff on top of cf?
I have not tried (ever used) any type of flocculant or clarifier, are any of those any good? or should I just take a couple days to mostly drain and refill?
