Our first tank was all new equipment and I wanted to get it up and running quickly, but this time around I'm taking my time with a smaller scale, cheaper tank. I found a re-built 40 bowfront stand which I'm re-purposing for my new 40 breeder build. The stand doesn't have proper access to allow getting a sump in/out - so the previous owner removed the bottom of the stand. This allow you to put the sump in place and put the stand on top of it, which is easy enough. However, I'm trying to figure out what I should do to protect the floors and seal up the stand/sump area. Should I put down some kind of platform under the stand? I was tempted to cut out a rough plywood section and maybe line it with some kind of waterproof material for limited coverage. Any advice is appreciated.
