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.
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.

Re: Too much DE in pool
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?

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

Re: Too much DE in pool
So . . . fix your filter.
Re: Too much DE in pool
If I could find what's wrong with it, it would have been fixed months ago. Are you saying that it will then filter the DE? That that's how I get it out of the pool?

Re: Too much DE in pool
I know that the filter has a leak - I've been looking for the source of it for about 3 years. But it's not any worse than it was, and this incident happened some time in March.

Re: Too much DE in pool
I'm not talking about a water leak. DE will not pass through a functioning DE filter.
In fact, it won't even pass a functioning sand or cartridge filter ( though it can DAMAGE cartridges!). I've actually used that fact for years to test sand filters.
Re: Too much DE in pool
Ah, OK, thanks.
Well, I can take it apart again, the 3rd time, and see if I spy anything. But I'm pretty sure it would have turned up before.

Re: Too much DE in pool
It's actually pretty straight forward:
+ You put DE in the skimmer.
+ DE shoots out of the returns.
+ Ergo, EITHER the piping is malfunctioning, and bypassing the filter
+ OR the piping is working AND the FILTER is malfunctioning.
DE does not pass THROUGH properly functioning DE filters.
Period.
But unless you REALLY know the filter . . . and how ALL the icky bits actually WORK . . . finding the bypass point can be a challenge.
