Hello everyone. My new 180 gallon tank is coming this weekend. I've already built the stand, but I was wondering what, if anything, I should put on top of the plywood to set the tank on. I've heard of people using Styrofoam. If thats the case what thickness should i go with? Any advise is appreciated. Ive atached a pic of the stand i build. Still havnt skinned the front or sides, but the top is 3/4 inch plywood.
