Ben - Great to have the forum up again, thanks for the work that you don't get enough credit for!

So, my above ground is 6 years old this year, 18x33 w/deep end (~15k gals).
Very warm winter in TX, added some bleach now and again and let it turn a bit green. No problem, except that it got warm quick and turned green-Er! Last couple weeks I've been vaccuming to waste the dead, white algae. Bleach, bleach & bleach, but the problem is just like some other posters, the fine algae is going through the sand filter.

That leaves a milky-white pool which I've been vaccuming every day and haven't seen the bottom of for 2 weeks (plus pump running 20hrs /day). I have the cleanest fine, bleached, dissolved algae south of the Canadian river! If I can only get it out of my pool without emptying it, which is another thing. Can't really vaccum too much to waste anymore, my water bill is bigger than my mortgage. I've tried clarifier but it doesn't do much.

So, do I replace the sand with new sand, or ZeoBrite?
One concern with Zeobrite is that I run a SWG and have read that salt is used to 'clean' ammonia from the ZB. Doesn't matter to me but --
Can you (Is anyone) using Zeobrite with SWG?

Thanks and hope to post pics of my soon-to-be sparkling pool! (It's gonna be 97 tommorrow!
