I have had a 55 gallon freshwater tank for my cichlids for many, many years and am pretty confident in my abilities to maintain a healthy freshwater tank. I just purchased a new 55 gallon tank on the weekend that I have started setting up for saltwater. I have live sand in it, enough instant ocean salt to have a salinity of 1.023. I have a GLO T5 HO
dual light with marine bulbs and am cycling the water with a Fluval 305 cannister filter system. I plan on having both coral and fish in my tank. I am unsure as to the next step. My pet store has just started getting in saltwater supplies and fish, so they are learning as well. I have read that I will need a protein skimmer, but am unsure what they do and what is the best brand to buy. I don't even know what type of corals or fish I should buy after my tank has cycled. HELP!
