depth of substrate for clean water

I would stick with the smaller grain mexican gravel from Lowes. They're at an affordable price of $12-$15 for 50lbs bag. Bio do grow on everywhere but proper filtration system is still needed.

that might be what ill do b/c i read that for proper bio filtration u need like 2-3" of substrate and gravel around me is kinda expensive and donst look natural at homedepot but yea screw the sand ill get the gravel thanks
