In my area, I was only able to find pool filter sand at pool supply stores. Home Depot and Loews didn't carry it. I've never used UGJ but have read if set up correctly they can work very well.lj1064 said:Thanks...so I guess the pool filter sand I can get at a pool supply or Home Depot? I was thinking of going w/a ug jet (I think that's the right term) That seems like it would keep a lot of the bad stuff suspended so the filter will take care of it. Any thoughts on the ugj?
