I love your reply here @JCTReefer. Hilarious. Love the passion!All good information.. I have no imperfections in my stand. I know this because I built it. Haha. And it is dead nuts level. That’s the advantage of leveling feet. And there’s 9 of them. Just for psi purposes. And there is no imperfections in the 3/4” HDPE sheet that goes on top of that. Perfectly flat. And there’s also zero deflection in the stand. The only imperfections would be from the tank builder. Lol!! Man, I wished they would warranty using your own stand like glass cages. I guarantee what I built is way more structurally sound that what they produce. That is my line of work. Anyways, I’m convinced to keep the foam with above comments. Thanks for chiming in @Joe Glass Cages.
