Ive had a 55 gallon fw tank for some time now and ive been reading around about salt recently. Ive talked to the guys at my local fish store about setting up a 75. I'm looking to do a fish/live rock tank. They are recomending I go with a aqua clear 110 hop filter and a fluval 306 canister. I'm still trying to get a good understanding of skimmers. Id like to do the right thing the first time around. Any advise would be appreciated.
