I read somewhere that you need styrofoam to help eliminate stress points on the plastic rims and help level the tank. Some even recommended to use 1/2" thick styrofoam for tank less than 50gallons and 3/4" thick for heavier tank.
Is this true? do you really need styrofoam ? anyone in here use styrofoam under their tank?
I have a 150g and would like to know before i fill up the tank. I Don't want to come home with a house full of water. if you do have experience with styrofoam, please let me know how thick i suppose to get. I heard you can find it at Lowes and Home Depot .
