Anyone have any experience with Silica sand as substrate? How does it do with canister (fluval) filters? any photos of a tank with silica sand?
thanks in advance
I have a 100lbs of silica (sandblasting) and 100lbs of pool filter sand mixed together. I haven't had a problem yet with my 2 fx5's and a wet dry.
It's a 180 and I wanted to have a clean look so I drilled holes and plumbed the fx5's through the glass. The intakes are 14" up from the bottom.
