A fish only tank can be kept.021-1.026. Compensate for evaporated water losses with RO/DI water. Keep the temperature, calcium and Alkalinity levels stable. Do not use commercial "supplements" other than water changes unless you know what you are doing. Algae blooms are common for probably the first 6 months of your aquarium, so don't be alarmed to find new algae growing. Just keep it clean and do about a 10 water change every week.

15 Let the tank "cycle this means you will need to wait until the water tests negative for ammonia and nitrite. Inserting bits of frozen fish foods in the sand essay bed can speed the cycle. (This is unnecessary if you added live rock. There are plenty of dead crustaceans and worms visit already inside due to shipping). This may take 1 to 6 weeks. Algae blooms can be a natural part of the cycle. Check and make sure the salinity is stable.023.026. This does not mean it can.023 one day and.026 the next. Find the salinity you want and keep it at that level. 1.025-1.026 is the optimum salinity for corals; a lower salinity is inappropriate for inverts/coral.
(Old tank syndrome happens when the sand bed has accumulated more detritus than it can handle and may result in a "tank crash" if pockets of toxic H2S are stirred up in the bed.) A 1-2" sand bed can also be used as long. Another way to go is not to add sand at all. This is called "bare bottom". It is much easier to keep the tank clean with a bare bottom, as you can easily siphon out the detritus. It's not as pleasing to the eye perhaps, but for many people, the ease of keeping it clean makes up for that fact. 14, add 'live rock' and arrange to your liking, approximately 20 of your volume. The rock can be placed on an aragonite sand bed, or alternatively you can add the rock prior to the sand. Live rock can be obtained biography online, from other hobbyists or at your local marine aquarium store.
Copper is toxic to most invertebrates; including corals, decorative shrimp, etc. 12, once you mix your saltwater and fill your aquarium, turn on all your pumps and let the water 'rest' for a day. It takes a little time for your salt to dissolve and your water chemistry to stabilize, and the action of the pumps will drive out excess carbon dioxide (which initially causes a low pH). You can add sand if you choose to, either before adding your water (if it is not a live bed) or after. If it is a "live" sand bed, add it after you have mixed your saltwater in the tank. Leave the skimmer off until the sand settles. A sand depth of 4 to 5" is recommended for maximal detritus biological processing (at this depth only seasoned hobbyists as at 4 to 5 inches many nasty things can grow as well -research aerobic and anaerobic sand beds for reef tanks). Some folks prefer the look of the sand bed, but don't want the possible "old tank syndrome" that can come with having a deep sand bed.

The chamber housing your pump is usually the one in which you will notice a drop in the water level due to evaporation. There are auto top off kits available to top your water off daily with fresh dechlorinated water(no salt). Alternatively, you can top off manually by marking where you want your water level to be and then keeping it full to that line with fresh dechlorinated water (preferably ro/DI). 11, prepare enough artificial seawater for the volume needed. Use only a good aquarium sea salt brand and purified water with a reverse Osmosis or R0/deionization Filter. Another option is to fill the tank with RO/DI water and then add the salt. The importance of RO/DI system cannot be understated.
Tap water can be used, but your aquarium is then at the mercy of whatever harmful chemicals may be. A good RO/DI system is not too expensive, and should be considered robert a necessity. A 100 gallon (378.5 L) per day model is a good choice, homework because you won't have to wait too long to make purified water which is a nice convenience. If your tank is smaller you can purchase bottled ro water at your local store. Use of distilled water is not recommended as most distillation units use copper pipes.
Additional powerhead pumps in the tank or external pump(s) should be installed to provide additional vigorous turbulent flow to otherwise stagnant areas, which is crucial to the survival of your future corals. 8, place a heater(s) in your sump, or the rear chambers of your tank. 9, consider using an aquarium chiller. The high intensity lighting used in reef aquariums adds a surprising amount of heat to the aquarium, making it harder to keep a reef aquarium 'cool' enough. Although heat issues are not as much of a problem in cooler countries like canada, you'd be surprised just how much the heat can creep up on a warm day in your tank. The point is to try to keep the temperature variation minimal.
The less your temp varies throughout the day and night, the more stable your marine environment will. 10, fill the tank with tap water partially to test for leaks. Run all your pumps. Turn the sump pump off to see how much water drains into. Use a piece of tape to mark your "maximum" water line. That is the maximum amount of water that can be in your sump before it overflows. You can also put a piece of tape down for the minimum fill line, which is the minimum amount of water required in your sump to get the pump to work and not blow air into your display. Run the water level somewhere between those two lines.

Don't rely on 'venturi' skimmers, unless they are high end models with very strong pumps. Don't bother buying gps 'canister' filters, often used on freshwater aquariums. Not only are they fairly useless in a marine aquarium environment, they can cause a buildup of Nitrates on their internal media that can negatively effect the aquarium. That being said, a canister filter can be used for carbon or other chemical media, provided it is cleaned on a regular basis. A skimmer quickly becomes cheaper than database salt-water changes. If the aquarium is not heavily stocked and does not have delicate (or very valuable) fish, try putting the skimmer and even the filter on a timer -though there must always be some circulation such as from powerheads-to allow everything to filter-feed during the day. 7, adjust the flow: Now is time to get a saltwater rated pump to return the water from your sump to the main tank.
The main thing to keep in mind when choosing a fluorescent T5 fixture is to make sure to buy one with individual reflectors. While the lights do put out a fair amount of light with regular parabolic reflectors, they become amazingly bright using individual reflectors. Many people choose to use a single color of metal halide, like 10000k, and will use a few blue (or Actinic) fluorescents to make the color more pleasing. Set up the filtration: On a smaller tank (less than 40 gallons) regular weekly water changes can be used in place of a skimmer. If you have chosen to buy a larger tank (40 gallons) a protein skimmer is a very important piece of equipment to purchase. Get a good quality about protein skimmer and place it in your sump or on the back of your tank if it is designed for. Do not skimp on this. Often protein skimmers are under-rated for the size of tank, so in practice a skimmer rated for a 100 gallon (378.5 L) tank is barely adequate for a 50 gallon (189.3 L) reef tank (especially one with many fish that get fed a lot). Needle wheel skimmers are a popular choice, and can be very effective for their size/cost.
lighting for most of the corals commonly kept, other forms of lighting are also obtainable and offer varying degrees of success. 250 watts bulbs will suit most common aquariums except for the deeper ones where 400 w bulbs provide more light e color spectrum of the bulbs (expressed in color temperature in Kelvins) is a matter of personal preference. Bulbs between 10,000 kelvin and 20,000 kelvin are the most popular, and the higher the kelvin rating the 'bluer' the color. Some claim coral growth is affected by the color, but corals grow fast and successfully on either end of the 'spectrum'. One halide bulb for every 23 feet (0.60.9 m) of tank length is usually recommended. 5, other types of lights to consider are fluorescent lighting, specifically high intensity fluorescents. Two popular kinds are power Compact and T5, or T5HO (meaning T5 high output). These can be found in many of the same color ratings as metal halide bulbs, and are often cheaper and produce less heat than a metal halide. A popular choice is to use both fluorescent and metal halide.
3, choose between acrylic or glass. Acrylic will scratch easily but is easier to drill and is much lighter. You can buy a tank pre-drilled, year or if you are handy do it yourself (using a diamond bit hole saw). Some fish shops and glass stores will also provide this service. A tank with an "internal overflow" is a big plus. These are often sold as "reef ready". It is better to choose a tank that is not too deep(e.g. 24 to 30 so you can reach the bottom easily; a tank that is wider will provide a better depth of view for a more natural look as well as have better light penetration. A second smaller tank (a sump) is placed under the reef ready aquarium and will hold all the equipment out of sight.
