Basically, I feel like leveling up in the filtration part of my tank. I'd thought about pluming a sump because the there's not too much space in the back. I had made this tread because I was wonder if I should even go the sump method. If I do, I just wondering what my main powerhouse would be down there. But seeing (by the man himself) that there is no "best" method, and it comes down to wants and needs, then I guess I'm satisfied. If I go with the sump, I'll probably use a skimmer and refuge, (and water changes?) I honestly feel I should just upgrade my tank at that rate, but I can always reuse the sump on a new tank. So, I'm very sorry for the confusion or if I had caused problems of sort. Thanks for the help! Much appreciated.
