Thanks Frankie, I have read up quite a bit, thats why I opted for a minimal amount of sand in the tank, the remotes a different biologically and im assuming reach a greater level of denitrification as well,the light issue seems more nuisance than beneficial, for depth? Ill end up with about 8'' deep but only 6''wide, if I had math skills I could figure out the lbs of sand but its roughly 7gallons, right on the mark
