There is not gonna be one definate answer to your question. Although there are a majority of people running tanks with sumps. Even the sumps are set up different with an endless list of combinations. I would do some research, find out what would work best in your situation, don't forget about maintaing the filter and tank as well. a fish only tank will be more forgiving than a reef tank but it's still no drop in the bucket. Also take equipment cost into consideration.
