go to your local hardward store, by a 10-12 inch piece of stainless steel "back strapping" (its an inch-wide thin strap of metal.) then simply line it up with your center brace, run 3-4 screws through it AND the plastic center brace, then cut a piece of 2x4 wood and then simply drill some scresws through the metal piece into the wood, push it up against the wall, and fill with water....tada!! problem solved. i will mention that for this to work, you will have to have the wood block wedged between the wall and tank, or else it wont hold. if you need a pic of mine i can upload it later tn
