Too much DE in pool

[SL Dan]

Alright. So no to the flocculant, then. You sure?

[PoolDoc]

If it IS DE, flocculant will NOT help. DE settles more quickly than flocc-ed algae . . . if you turn the pump off.

I haven't read this thread carefully, but I read enough to know that you need to verify that it IS DE, and not dead algae. If you grab a pinch, DE will have texture and substance; dead algae will not.

And IF it IS DE, something's wrong with the filter, though it could just be a mis-oriented valve.

[SL Dan]

Well, it wasn't in the pool til I cleaned the filter. Then it was in the pool immediately. It's not dead algae, as far as I know. It's been a couple months, and it immediately clouds the pool the minute I stir it up. It's greenish now, but it used to be more-or-less white.

The strange thing is that I could swear I saw it spouting back into the pool the minute I put the DE in, much faster than the water actually goes.

===========================

BTW, this equipment is dead simple. Just off and on. If by a mis-oriented valve, you mean one of things on top with multiple settings (I have one of those on our pond), it's not that.

[PoolDoc]

It really sounds like you have a hole in one of the membranes (or fingers?).

But again, if it's DE, it WILL have 'texture' when you pinch it between your fingers. And, it will NOT be green.

So, I'm thinking you have a filter problem AND algae.

[SL Dan]

Right, I have algae NOW, but a few weeks ago I had the same problem and it wasn't green. I've taken the filter apart twice since the problem began, inspected all the grids, and they're fine. But of course, you're right - I must have a filter problem.

But my original question was: how do I get the DE out of the pool?

[SL Dan]

Oh, and I know it's DE because, when I vacuum the pool, there's an excessive amount of DE in the leaf trap.

[PoolDoc]

So . . . fix your filter.
