i have a setup in my tank which has gravel and i decide i was going to replace that with sand. ive been reading around the forum and people seem to use Silica sand because they say its clean. with all this in mind i went to home depot and asked them for that sand and they said all the have is this.....
"pavement sand"
is this okay for the fish? is it clean or safe?
