Do I need to set up the skimmer for cycling a tank using live rock? The reasoning behind this would be to allow me to purchase a better skimmer - for a larger tank. I'm going to use mostly ReefSaver Eco rock (dry) and seed it with a couple pieces of wet live rock. I'm assuming cycling is similar to freshwater cycle, so I wouldn't need to do water changes while it cycles. Background - 55g tank, planning on FOWLR. I will buy 50 lbs dry rock and 25 lbs live rock. I want to build a sump for it, probably 30g. Would like to keep options open for larger tank in the future - with minimal extra expenses for the larger tank. Also, do I need more live rock than that since the sump is an extra 30 gallons?
