well what i would do if you plan to have corals is upgrade your filter when you can because, the AC 200 or AC 50 (depending on when it was made it will have 2 diff numbers) is a good filter, however IMO you cant beat a fuge with some live sand and cheato and other vairous live filtration. Having a big skimmer in that sump wouldnt hurt also, you could even run the powerfilter that you hav right now and run a fuge at the same time. BTW im not calling down your equipment, im just making a suggestion on upgrading. I dont suggest skimping out on equipment to save money, that would just hurt you in the end. Buying better equipment and being patient to save the money for the better equipment will help your tank thrive in the long run. theres a thead in the introductions forum, and its called mistakes not to make or somthing along those lines. You could read that and see what ppl have to say... keep up the good work and keep an eye on that clown...
