I have a 90G with a 29G sump. I'm currently using an Aqua C Remora in the sump, but I want to replace it. I won't have enough space in the sump so my new skimmer will have to run outside the sump. I've been looking at the AquaC - EV180 and the MR-1/MR-2 Skimmers. I don't want to have to adjust or clean the skimmer everyday. I want something that I can set and forget. Aside from cleaning the collection cup I would like the maintenance of the skimmer to be minimal. What should I get?
