-Fill a large bucket with clean, dechlorinated water.
-Using a hydrometer, add salt. Your goal is a specific gravity between 1.020 and 1.023.
-Fill your tank with the saltwater, leaving about an inch at the top.
-Start the filter system.
-Add the heater and thermometer (75* N 80*)
-Let everything run for at least 72 hours and get the temperature settings right and the water moving.
-Cycle the aquarium. A just-set-up fish tank lacks the bacteria that it needs to form a steady biological cycle.
-Add your fish when the chemical levels are all okay and the tank temperature is within suggested limits (2 to 3 weeks)
-Buy a powerhead. In saltwater aquariums, water movement is an absolute must. Be careful not to get one so big that it causes a whirlpool effect.
-Get a protein skimmer, which is a necessity for marine tanks. This removes organic debris from the water before it has time to convert to nitrates.
-Keep in mind that you'll also need an external water pump and possibly an air pump for your skimmer.
