Hello Folks, I finally purchased a plastic tank to replace my below deck aluminium one that rotted out. The info sheet that came from Moeller specifically states "do not foam in" because the tank expands. I have removed all the foam and glassed in resin coated blocks covered in heavy duty vinyl for the tank to sit on. The problem is, how do I keep the tank from moving from side to side and back and forth? I don't have much room on the sides (maybe 1.5 inches) or the ends (2 inches). The tank is 52 gallons and is 6 ft. x 2ft x 11 inch belly tank. Any ideas? I'll try to get a pic posted to give a better idea of what I am dealing with. <br />Thanks in advance...
