Just occured to me that we have done nothing to our sand filter since we built our pool in 1999.

We have a good bit of sand in our pool thanks to our dog that loves to run across the steps to cool her belly and take a drink and evidently wash her feet at the same time.

I have used Pool Buster with some success in getting it out but I wondered after feeling the texture of the sand and seeing it, if some of it was coming from the filter...

Also a PoolBuster question...do they make a filter that will capture sand? I have used batting in the one I have but you can still see it blowing out the side.
Thanks!
