Is anyone using a brand of filter sand called 'Palmetto'? It was one of the only reasonably priced options I could find local to me. There were NO SPECS at all on the bags- it is just labelled 'Palmetto filter sand'. I sourced it from a longtime local pool builder who said he uses it with all of his installs. The manufacturers website doesn't even offer any specs. Does anyone have any knowledge or experience with this sand? I went ahead and loaded up my Hayward S244T with 300# of it, and it seems to be doing fine. Just wondering if anyone else was using it, and what they thought of it.
