hi guys, i've looking for silica-free sand, but my local home depot and lowes don't have them. However, i found kolorscape sand by old castle and quikrete sand. They both contain silica, and quikrete is 2x cheaper. Which sand do you recommend for my tank?
 
If your looking for silica free sand why are you considering either? Spend some dough and get some real sand from the fish store. Aragonite.
 
I used QuickCrete for almost a year. I blended it with LS, and never had any problems. I had about a 50/50 blend.3
