i have like 90lbs of white silica sand, the quickcrete kind.

sold at most hardware stores as a concrete additive.
fine grain, very white and uniform.

can i use this in my tank?

the only reason i ask, is i know silica can and will release silicates into the water. A simple curing of the sand should work? shouldnt it?

let the sand sit for a few days until the silicates are leached out, then rinse, and add to the tank?

any info appreciated.
