Im setting up a 265gal (south American cichlad tank) in my basement. I just got a fluval fx-5 and are planing on adding a second canister with a 36 watt uv turbo twist. I plan on using about a inch to inch and a half of gravel substrate with aerators in the tank. my main concern is leveling my stand. It is a perfecto open top it has three five inch supports that make contacts with the tank frame im about 5mm off front to back and 5 side to side. how or should i use Styrofoam to level or should i put a sheet of ply wood down first. Please help this my first large tank other than several 55 gals over the years. i have never use Styrofoam in a set up before but i keep reading about it.
