Starter Reef

Setting Up a First Marine Aquarium or Young Aquarist's

Tank Using a Simplified, Natural Approach ften perplexing for those who haven't tried it before, setting up a new aquarium can be simple when done in logical, unhurried steps. The accompanying photographs illustrate a straightforward sequence one might use to create a simple reef system, using the techniques discussed in this book. The theme we have chosen is a bit of Micronesian deep fore-reef habitat, which will be housed in a 20-gallon aquarium — a tank size that offers enough room to create an interesting ecosystem but is small enough to fit a beginner's space and budget, with no expensive lighting or filtration equipment required.

Step 1: Assemble the Equipment

After visiting the local aquarium shops and developing a plan and budget for your system, you will first acquire the necessary tank and equipment. Under no circumstances will you buy the gear (hardware) and livestock (software) on the same first trip. Unlike the typical setup for a child's goldfish bowl, you must have a marine aquarium up and running, with the water quality stabilized, before you bring home the first live organism.

Step 1: Essential components of a basic, inexpensive, beginners natural reef system, including 20-gallon glass aquarium, simple light hood, external skimmer, small powerhead, thermometer, hydrometer, test kit, salt, and aragonite or coral sand.

Step 2: Prepare for Filling

• Rinse the tank with freshwater. Never use soap or commercial cleaners to clean an aquarium. (If you need to remove a stubborn deposit, use a little white vinegar. sin-gle-edged razor blade can be used on a glass aquarium, never on acrylic, to remove anything adhering to the glass. Rinse again with freshwater after cleaning.)

• Apply the background. Before the aquarium is positioned against a wall, take the time to install a background, which will obscure any distracting wires, filtration gear, or man-made wallcovering behind the tank. Pet shops carry waterproof paper or plastic background materials in sheets or rolls; there are many decorative choices, but I recommend a simple black or dark blue as the best choice for a novice. First, clean the outside of the tank glass thoroughly. Fingerprints or splotches will be remarkably apparent against the background when the tank is set up and illuminated.

Use small pieces of tape to hold the background in place, then use duct tape to completely seal the background to

• Being careful to first wipe up any spills, plug in all the equipment.

Check to be sure that the skimmer and powerhead are working properly. Dont expect the skimmer to produce foam at this point. It won't. Adjust the thermostat on the heater, following the manufacturer's instructions. Unless you are attempting to duplicate a special environment, 75 to 78 degrees F is a good starting range for a typical marine tank. (If the heater does not provide temperature settings, you will have to check and readjust the thermostat several times over the first day or two until the correct water temperature, as shown by your thermometer, is achieved.)

Hydrometer Correction Formula

Step 4: Add Salt Mix variations. For example, a hydrometer reading of 1.0240 at 24 degrees C calls for a correction factor of +0.0021. Thus the corrected density reading is 1.0261. The salinity, from the table on page 122, is 35 ppt, the same as full-strength Most salt mix formulas require a little more than 2 seawater.

Assuming you select cured live rock, all you will need to do is remove it from the container in which it was transported and place it directly in the tank. Try to have an open arrangement that allows for water movement around each piece, rather than a solid "brick wall" effect. Use your imagination. Since the habitat we have chosen for this tank is a deep fore reef, try to create a cave, arranged so that a view into the cave will be the focal point of the tank. Here is where your fishes or shrimp will likely retreat to avoid disturbances or to sleep.

• If possible, position the powerhead and skimmer so they will be hidden by the rockwork, and direct their currents to flow either across or through the reef structure.

not absolutely necessary — the dust is harmless — but the aquarium water will clear up more quickly if the sand is rinsed in this fashion. As each batch of sand is rinsed, add it to the tank, creating a uniform layer on the bottom. Don t worry if the tank becomes cloudy; this is virtually inevitable at this stage and it will clear up in a day or two.

7 s Once the rock and sand are placed, appropriate first inhabitants are herbivorous species that will industriously attack the algae growing on the rock and tank walls. For this tank, 10 snails and four tiny hermit crabs would be good choices. You may be able to order Pacific species of both kinds of organisms, but if necessary, make do with Astraea snails and Blue-legged Hermit Crabs (Clibanarius tricolor), which are native to Florida. After obtaining specimens, float them (in their plastic bags) in the tank for about half an hour, then release the animals, but not the bag water, into your aquarium. Wait a week before adding any other specimens. If no algae growth is apparent yet, add a tiny pinch of fish food for the benefit of the hermit crabs.

Many, if not most, marine systems are started with lished, healthy reef aquarium. Spread this in a layer on top of the aragonite sand.

The Feather Dusters are filter feeders, and the Scarlet Cleaner is a scavenger, so feeding need not be too frequent. Once or twice a week, a very small amount of frozen fish food can be added for the shrimp. The Feather Dusters will feed on bacteria and other small particles stirred up during maintenance of the tank. Plan on doing a 20% water change about 30 days after the live rock is first added and each month thereafter. Check the nitrate level each week and start doing partial water changes if it rises above 20 ppm. This may be more or less often than every month, depending upon the individual circumstances of your tank. Check and record the pH every week, and check the tempera-

Also shown is a Blue Devil Damsel (Chrysiptera cyanea), the classic beginner's fish and an ultra-hardy selection. An alternate choice might be a pair of cardinalfish, also quite content in a small tank.

Remember that any new specimen will require a few days to become accustomed to its surroundings, so do not become alarmed if the fish hide and/or fail to eat for a brief period. Healthy specimens should start feeding within three or four days. If there appear to be problems, consult with the dealer from whom you purchased the fish.

Purchase a selection of frozen foods at the same time you obtain the fish. Feed a small amount each day, observing carefully to make sure that all the food is consumed within an hour of feeding. Watch for normal behavior and check tank conditions (including temperature and equipment functioning) at each feeding.

Congratulations! You have now succeeded in establishing your first natural reef aquarium.

Upgrading the Hardware

With only a couple of modifications, the 20-gallon system just described could easily become a typical

Indo-Pacific fringing reef, representing a shallower habitat between the shore and lagoon. First, install a four-lamp fluorescent lighting system instead of the single strip light in the previous example. I would also recommend installing a second powerhead, directing the outflow perpendicular to that of the first powerhead (to the extent permitted by the rockwork) and control both powerheads with a wave maker.

Upgrading the "Software"

After your starter reef system is established, it will begin to exhibit periodic algae blooms. If you follow my advice on pages 136-138, however, the algae blooms should abate after about six or eight weeks, and small patches of purple and mauve coralline algae should begin to appear here and there. Once this coralline algae growth develops, you can add an assortment of soft corals and mushroom polyps. A variety of these might be found in any shallow, fringing reef habitat. You may choose to populate this reef with different or more exotic fish species, but use caution: a 20-gallon system with this filtration system will support only a light load of fishes and/or mobile invertebrates.

As you gain confidence with your skills as a reef aquar-ist, you will likely want to set up a larger system, and to try your hand at keeping a wider variety of species. Relax and enjoy. You are well on your way to a lifetime of learning and pleasure as you gain experience with the denizens of Earth's most interesting ecosystem, the living coral reef.

The COMPLETE guide to Aquariums

The word aquarium originates from the ancient Latin language, aqua meaning water and the suffix rium meaning place or building. Aquariums are beautiful and look good anywhere! Home aquariums are becoming more and more popular, it is a hobby that many people are flocking too and fish shops are on the rise. Fish are generally easy to keep although do they need quite a bit of attention. Puppies and kittens were the typical pet but now fish are becoming more and more frequent in house holds. In recent years fish shops have noticed a great increase in the rise of people wanting to purchase aquariums and fish, the boom has been great for local shops as the fish industry hasnt been such a great industry before now.
