It is relatively EASY to learn about keeping a tank of marine fish – as long as you have all the relevant information. http://www.saltwater-marine-aquarium.com/ When choosing an aquarium its size will depend on the location, but the larger the better.The location in turn will determine to some extent the type of lighting needed. http://www.saltwater-marine-aquarium.com/ Decide between mechanical, biological, or chemical filtration system, or a mixture from plenum, fluidized, deep sand bed or under gravel filters. http://www.saltwater-marine-aquarium.com/ Choose your water supply wisely with RO/DI pre-filtered water or get a water purification filter. http://www.saltwater-marine-aquarium.com/ Consider surge devices or powerheads to circulate the water. http://www.saltwater-marine-aquarium.com/ Now you will need a hydrometer, a thermometer, a test kit, salt mix, calcium, iodine, air pump, tap water filter, protein skimmer, and water conditioner. http://www.saltwater-marine-aquarium.com/ Now make a list of all the fish, invertebrates, crustaceans and corals that you are attracted to, and learn everything there is to know about them all. A reef tank can accommodate fewer fish, but plenty of invertebrates, live coral and anemones. The diet of many marine fish is coral and sponge so beware. Once fully set up with the live rock and plants all added the system needs to be fully tested. A separate small quarantine tank should be considered to put your new fish in first. http://www.saltwater-marine-aquarium.com/ Set up and follow a regular maintenance routine to avoid water quality problems. Having studied the subject, you should know not to put in too much live rock or fish at once. http://www.saltwater-marine-aquarium.com/ Learn how to tell if a fish is healthy. Sick fish usually don’t eat. Know what type of fish and how many your tank can comfortably hold before you go out to buy. Learn about the requirements of each type of fish and it’s suitability for your system. Some fish are territorial, others placid, and some are aggressive such as sharks, pufferfish, lionfish, triggers, foxfaces, the grouper series and small eels. Consider all of this carefully. Remember, the larger the tank the least chance for aggression. Always add food slowly to avoid algae growth, and don’t overfeed, as this can kill many species. http://www.saltwater-marine-aquarium.com/ The type of lighting you choose is dependant on the type of organisms in the tank. To help maintain the intense colours of the coral, CF or MH lighting is best. Regulate the tanks photoperiod with a timer. The recurring cycle of light and dark periods should be no more than 10 hours. If the light periods are too short, the corals may not get enough nutrients via the UV. Too long creates algae on the bottom of the tank and stresses the corals. Place a sheet of glass or UV blocking acrylic between the bulbs and coral to raise the lighting. http://www.saltwater-marine-aquarium.com/ This guide is for aquarists who are interested in keeping a fish only aquarium.
