Hey guys I'm going to be setting up my first big tank and only my second tank so far. I'm not really sure on what equipment is best, but my goal is to have a system that doesn't need many water changes. The tank will be 100 gallons, 60x18x23 and I'm thinking a 55 for the sump and a RO water tank next to that. The 55 will be half filled and have 3 chambers, skimmer, fuge, return. A total of around 130 gallons, what I need to know is what skimmer and other equipment will keep the water really clean so I don't have to do more that one water change a month. I will be using natural seawater and I work a lot so I won't have much time to go to the pier. Will a eheim 1260 work with this big of a setup? What size drain hole and return holes should i have drilled? Its going to br a corner overflow and I want it dead silent. Any help is appreciated! Thanks
