If you've done cichlids, you can do salt pretty easily for a fish only tank. The pH is 8.2, the equipment and filtration is pretty similar, you're just monitoring salinity. Coral add more chemistry like calcium, dkh, magnesium, and water flow, feeding, and lighting requirements. They're lots of fun. Kinda wish I hadn't sold my 75 gallon setup. I thought about setting up a 2.5 gallon nano reef or a 40 gallon reef, but have to buy most of the equipment over again. I did keep my protein skimmer though.
