OK, I have a 27' above ground pool. Hawyard sand filter. I've just started getting it ready, the pool was left uncovered over the winter. I scouped out the leaves from the bottom, then there was a nice layer of green algae on the bottom.

Also, before I started up the pool, I replaced the sand in my filter hoping it would prevent the problem I had last year.

I started up the filter, added 8 bags of shock, and now the layer of green algae is a layer of sandy-white algae.

I bought a new vacuum and hose today and tried to sweep up the white stuff on the bottom. Within seconds of running the vacuum, my filter starts pushing the white algae back into the pool thru the return. So my vacuuming is pointless since it's just blowing it back into the pool.

Maybe I'm getting more out that I realize, but it doesn't look good.

Last year, I had this problem and found it easier to vacuum the pool with my filter on backwash, thus sending the stuff I vacuum along with alot of water out in the yard. The problem with this, was I would have to stop what I was doing, refill my pool up overnight before I could finish the job.

So I'd love to learn how to vacuum my pool without losing all the water and without blowing the dirt back into the pool.

Should I have tried to vaccum out the algae before I shocked it? Maybe shocking it caused the particals to become smaller and the filter isn't catching them? Just a guess.

Any ideas on what I can do to help?
