I know that on AC this question gets asked everyday but I can't find any info there and I don't want to get yelled at! I'm setting up an 125 gallon aquarium and I'm going for a hardscape. So My question is what's an affordable bulk black sand, I'd go with pool filter sand if it came in other colours though. I might have some cats in it so I'd perfer sand that doesn't cloud the water easily, Thanks!
