Sand Filter Troubles

[duraleigh]

Robbin,

It is possible you are going down the wrong track. If you posted some test numbers, that might be very revealing. If you could do FC, CC, CYA, CH, and pH....then tell us how many gallons in your pool and if it's concrete or vinyl.

You simply might need a good dose of Chlorine.

I'm not sure I agree with the floc, I'd like to Identify it before trying to cure it.

The chances of it being your sand are extremely remote.
