I don't know how to get rid of this stuff -- large amounts of fine dirt at the bottom of our in-ground pool. It didn't seem to be an issue until we changed the pump this year, to a variable speed pump.
We've got a new Intelliflo pump, and we've got an old Polaris that works about the same as it ever did. It mainly picks up leaves and stuff. I always assumed the finer stuff went through our DE filter. But ever since the pump was installed, we've had constant problems with this fine dirt covering the bottom of the pool, which we never had before.
I'm constantly brushing it when the pump is on, and it temporarily "disappears" (although there's so much of it that the pool water is cloudy from it, so it doesn't really "disappear") and I hope that the filter will filter it out. But it doesn't. It just settles back down.
Sometimes I run the pump at top speed for many hours, and keep going outside to brush it up again as it settles. But no, it doesn't get filtered out. It's horrible.
I would think the filter should be taking care of this, and yes the filter was recently cleaned and is not due for another cleaning for at least a couple more months.
What could the problem be? Why should be be a problem only this year, and with a brand new pump? Is there some way to clean this dirt out of my pool? Is the filter supposed to be doing this? This has driven me crazy all summer. I'm tired of brushing and brushing and brushing and none of it going away. Thanks!
