Oops, I am doing it all wrong then. I better tear down my tank before it fails. I only have a 15G sump on a 75G tank. 
Generally, it's recommended to go as big as you can on a sump. However, space under a stand tends to be a limiting factor, and many people (or their significant other) do not want to see a second tank set up nearby as a sump. IMO, any size sump is better than no sump, as long as it's put together and plumbed properly so it doesn't flood during a power outage.
