I am starting to get more and more aquariums and it takes up a lot of space. I am thinking about getting a rack to put all my aquariums on. I don't any experience in woodworking or carpentry so I don't trust myself with tools that could cut me in half. What racks do you use that you could buy in stores? How much weight could you use on them? For example, if a rack is rated 1000lbs, is it safe to put 1000lbs of stuff on it?
