I have a 25k in-ground pool, 1hp pump, about 30-40 feet of head, so my hayward pump is going 50-70ish gpm (from their chart anyway).
I had a HUGE problem with algae this year, and no matter how much I shock it, it's not clearing up. I've tried everything. Crazy amounts of shock and bleach. It's much better than it was, but still, only about 6 feet of visibility. Even the 3 feet of shallow end is cloudy.
No mount of classifiers has helped.
I just don't think the algae is being filtered out. I think it's mostly dead, but the water will not clear. Running the pump 24 hours doesn't do much. It's a sand filter which freshly replaced sand.
I was looking at D.E. filters, which I've owned in the past, as well as cartridge, which I've also had (a very old model from 20+ years ago). This is my 3rd in-ground in a row, 25 years of pool ownership.
I was actually leaning towards cartridge filters over D.E. and came across this:
Reliant® RSC Series 425 Sq Ft "Quad" Cartridge Filter - FREE SHIPPING!
Never heard of that brand, and couldn't find any reviews, so I was weary, but it's like $150-200 cheaper than Hayward and Pentair.
Any suggestions would be appreciated. Money is tight and I really don't want to replace the Sand filter, but I've always hated them. My first pool had the same cloudy water problem with a sand filter. I replaced the filter with a D.E. and it was crystal clear 8 hours after installation, so...
