This can be a disappointment for new saltwater hobbyists who are use to stocking their freshwater aquaria full of fish–you won’t be successful doing that in a saltwater tank. Saltwater tanks require you to accept that fewer fish can be kept in the system.
Saltwater Fish: Marine Aquarium Fish for Saltwater Aquariums
Besides direct sunlight, metal halides are about the most intense light we can get right now over our tanks. Perhaps they will get LED aquarium lights working in the near future, or become more practical, which should hopefully make it cheaper to run our aquarium reef tank lighting systems without any added heat. At any rate, the lighting setup for you saltwater reef tank is going to be one of the largest cash outlays (can get very expensive) and lighting is one area you should spend some serious time on while researching the corals you would like to keep. Look into the purchase price, and ongoing maintenance costs such as how much it will cost to run those lights by looking at how many watts the light use and how much replacement bulbs are going to cost. These are serious considerations and may very well influence your decision to purchase a particular aquarium light setup.

The water, obviously, is a very important component of your tank set-up. The salinity of your water is very important for keeping your tank friends happy and healthy. You can buy great, easy gadgets to calculate the salinity of your water so you can check yours occasionally to avoid evaporation or low salt content. Your salinity should be kept at about 1.021 to 1.026 S.G. (specific gravity). You should adjust your salt content accordingly if your tank's salinity falls outside of this range. You can buy aquarium salt and mix it in with your water to start out. However, you have to keep in mind that the water in your faucet contains things like calcium that can be harmful to your tank. Purchasing a large bag of aquarium salt is about $15 or $20 and lasts about three months with the initial set up and water changes. The safest and easiest way to get saltwater for your tank is to buy it by the gallon at your local fish store. Most stores have premixed water that is the correct salinity and is mixed with purified water. It costs about $2 per gallon at my local pet store.
