I'm moving soon, so before setting my tanks back up after the move, I want to get new stands. I've got two 120s, and may possibly upgrade one of those to a 180 gallon. 1) Which would be best in terms of strength and longevity ??? Is "stainless steel" actually stronger than "regular steel" ? 2) Is stainless steel less prone to rusting ? 3) What are the Pros, Cons, Pitfalls of using one material over the other ? (I've always had wooden stands in the past, and most retail stores use wood for their displays too) 4) I've considered T-Slot Aluminum, but I'm not convinced that they won't fail on a large heavy aquarium 5) Any other considerations ?
