I need to add rocks to my soon-to-be Tang tank. It's a 33gal, standard footprint, with about a 1" layer or aragonite sand on the bottom. I'm not sure how many I'll end up adding, but they're good sized rocks and probably 40-60lbs all together. I've never had issues or worried about the weight of the rocks on the tank bottom, but I've always had sock set ups in tanks that had a solid-topped stand. This tank now is on a very solid wood stand, but it's the type that just has a lip around the edge to support the rim of the tank, leaving the glass bottom of the tank totally open (like the example I've attached). Do I need to worry about the weight of the rock work on an open-glass bottom? Should I take the tank off the stand before I load it up with rocks, and build a "top" or at least a couple braces across the middle section that will provide support for the entire under side of the tank?
