Did you ever get an answer to this?Flabbergast!! Sorry to thread dig like this but what's the highest anyone has gone with 1" cell cast and a braced top? I want to start a plywood/fiberglass tank and I can make 1" work in my price range but really want to go 48" high so figuring at least 40" to 44" on the acrylic by 96" L. If I "have" to go 30" I will but I will be greatly saddened.
Im planning on building a 12x4x4 plywood and was planning on using 1 inches as well. Was hoping to over brace and allow at least 8 inches of overlap on the tank to really hold it in place. I was hoping to get at least 40 inches of viewing out of the 48 inch width
