We were going to use Zeolite but the 2 pool stores in my area didn't carry it and I didn't feel like waiting and ordering it online. I had emptied out my sand filter last year because of concerns of a cracked lateral. Ended up being a crack in the main trunk that the laterals screw into. Then just refilled with regular pool sand. I'm still not convinced it's the filter putting the dirt into the pool or the dogs/kids running around outside. Our pool sits at the bottom of a small hill so it would be really easy for it to settle.

I tried panty hose on the return for 2 days and never had much in it...although the fine dirt would pass right on through.
