Newbie here - Intex 15'x48" Ultra Frame AG with a Krystal Clear Sand Filter Pump (3000GPH) - Haven't even set up the pool yet, but plan to this weekend. I can't decide what type of sand to buy. Maybe I'm overanalyzing things, being a newbie pool owner and all, but I have read bad things about some brands so I want to try and get it right. I know I need #20 silica. It sounds like I need to steer clear of the Quikrete brand. I'm on the fence regarding the HTH brand. Aqua Quartz has decent reviews. Any personal recommendations?? Thanks!!
