my oppinion,,,,,
take your time, buy the right equipment for your set up and you wont have any problems, at first you'll have to tinker with it on a daily basis,just to "work the bugs out" but after that, you shouldnt have any problems, we havnt had any problems thus far, i have a 125 gal. fish only with a sump, and in it i have a skimmer,uv sterilizer, return pump magdrive 9.5 a powerhead to operate the uv sterilizer......All in the sump, and no problems... we just do what i call prevenative maintenance, that will assure that you will not have any problems arrise... and it looks nice and very clean,,,pretty simple huh ? good luck....
