Ok...question for you guys. I got a used 135 from someone breaking down their tank here and have had it sitting in my garage until I was ready to use it. Got it ready to go, brought it in the house, put it on the stand and noticed there is a gap along the front top rail, about 1/8th of an inch at it's biggest point. It probably runs a good 4 feet of the length of the tank, and gets smaller towards the ends. What are my options to get this shimmed? Or do I have to scrap the stand and start over. It's the standard Oceanic oak stand if that helps for a frame of reference.
I tried putting in about 20 gallons of water to see if it would level out once there was some weight in the tank, but it hasn't budged and I'm too nervous to keep filling this thing until there isn't a gap.
I've read somewhere to put a piece of 3/4 inch plywood across the top, and shim underneath that, then put the tank on top. Or could I even use 1/2 inch?
Someone else mentioned using water putty.
Any ideas?
