Upgrading from my 75 gal. tank to a 120 gal. The 75 has a deep sand bed ( 4-5 inches ) and don't think I want to do this again. I'm looking for suggestions for depth and type of sand to use if I go with a more shallow bed. Is there a calculator to determine how much sand I would need for a particular depth?
