Hi everyone,

I said I want low maintenance tank, but can't stop messing with my tank!

I'm switching from black inert gravel to black flourite sand. Completed 2/3 of the tank last two days and it does look very nice. I'm giving it several days before I change the third section. My question has to do with the final third. I stair-stepped it up with slate rock and the gravel is about 4 inches deep. Is this depth o.k.? I'm considering replacing only the top half with the sand as I thought I'd read that deep sand can cause problems. Any truth to that? Should I do anything differently, any suggestions?

Thank you,

it's fine, Tom had the substrate up to a foot feep at the back on the big 1600gallon he did!

Excellent! Thank you...
