How to Setup a 50-55 Gallon Fish Tank?

The next step after purchasing a kit is set up your aquarium, and you can follow the steps below:

Identify a location for the aquarium and stand

Choosing a suitable spot is vital for the health of your aquatic pets. A suitable place will be where the amount of light does not get excessive, and the temperature remains relatively consistent. A lot of light will facilitate excessive algae growth and make maintenance difficult. You can choose an interior wall that is far from bright sunlight.

Ensure there is at least 5 inches between the wall to accommodate the filter.

Do not place the tank under a vent, as dust will collect in your tank. The vent will also make it hard to maintain constant water temperature.

The tank location should be close to an outlet to make maintenance easier.

Install the Filter

The kind of filter you have will inform the installation method you use.

Put the filter plate in the tank for under-gravel filters and ensure that the lift tubes are fitted. The tubes are mostly designed to fit the tallest tanks, so you may cut them to fit your aquarium. The tubes should be cut such that the tops will be below the surface of the water once the tank is filled. Attach the pump airlines into the appropriate lift tubes.

If you have an external power filter, install it at the tank’s back in a setting where the outflow will evenly spread the water.

Add the Gravel

Your tank should have around two to three inches of gravel at the bottom to keep the aquarium healthy. You can source for cheap gravel from pet stores.

It is vital that you wash your chosen gravel. The tank’s water will clear faster if there is less dust in it. Most beginners forego this step resulting in their tank being cloudy once they get their aquarium running.

You can use a hose with high pressure to spray the substrate directly in a bucket. Wash it by moving your hands in a circular motion. When the gravel settles at the bottom, remove the dirty water. Repeat four to five times and check if the water gets clearer. It is not unusual for some substrates to still cloud the water even after washing several times. Silty and fine substrates will naturally settle in the tank over time. Refrain from using soap as it is harmful to fish.

Slope the gravel upward toward the tank’s back. Spread the gravel in an even layer across the entire surface of the filter. Add a bit at a time since it can scratch the walls if poured in too fast.

Add Plants and Decorations

If you intend to keep a planted tank, add the plants at this stage as it is best to avoid adding any kinds of stress to the aquarium once the fish are in. Plants will even contribute to the health of the fish.

Ensure that any decorations you add are designed for aquariums. For plants, submerge the roots in the gravel, and leave the stems and leaves above water. You can add decorations like driftwood or rock, but they should be thoroughly cleaned.

Fill Up the Aquarium

Once the plants are in, the next step involves adding water. You can add little water to start so that you can spot any leaks. Fill the tank to just under its rim, and leave a gap of 1 inch.

You can use a de-chlorinator after filling the aquarium because chloramines and chlorine can fill up over time. Choose a high de-chlorinator to preserve the aquatic life in your tank.

Start the Filter and Add the Heater

Add water to the reservoir’s filter, and turn it on. You should see the water circulate after several minutes. Water should begin moving vertically in the lift tubes if you have an under-gravel filter. You can check the temperature after an hour or two to ensure that it is still in the desired range and that the water is circulating appropriately.

Your heater will attach to the inside of the tank via suction cups. Position it close or at the mouth of the filter discharging water to ensure that the water is evenly heated.

Most of the thermostats on the heaters in the market will come already set at a temperature range of 70 to 77 degrees Fahrenheit. Plugin the heater and set up your thermometer. Only turn it on with the tank entirely filled in with water.

You can get the fully-submersible heaters as they are easy to use, and one which has an adjustable thermostat.

Source for an appropriate for your aquarium, and place it above or on the tank with the timer set for not more than 8 hours every day.

Cycle the Aquarium

Cycling your aquarium will facilitate the build-up of denitrifying bacteria.

You can either opt for fishless cycling process or use fish.

In the case of a fishless cycle, biological waste is added manually while the water level is monitored. Once you Setup your aquarium, add a sprinkling of fish flakes and wait for several days as the flakes start to decay and release waste products. Test the water for ammonia after some days. The recommended level is three parts per million (ppm). Add more flakes if the water does not have enough ammonia.

Beneficial bacteria will soon start to grow in the tank, and they will reduce the ammonia concentration. Add more flakes whenever the level of ammonia falls below the recommended level.

Begin by testing nitrites after a week by using a commercial test kit. The presence of nitrites will signal the start of the cycle, and you can continue adding ammonia.

The final step of the cycle will involve the conversion of nitrites to nitrates, where the latter is not harmful to fish. You can then add the fish slowly as nitrite and ammonia levels fall to zero.

If you decide to use fish, populate your tank with hardy fish like X-ray Tetras, Zebra Danios, White Clouds, and most guppies. These species will produce waste and survive the initial high concentrations of toxins as the beneficial bacteria grow. Ensure you do not overfeed the fish, as it is not recommended to have left-over food in the water. Use test kits to track the toxin levels.

The cycling process can stretch for two to eight weeks. When the ammonia and nitrite concentrations at 0ppm, you can source for expensive or exotic fish. If the ammonia concentrations have not dropped in the eight weeks, the problem may lie in overfeeding, ineffective filtration, and overpopulation.

Maintaining the Aquarium

Your tank should not be overcrowded, and you should not overfeed your fish. Water changes are also important to preserve the quality of the water in the tank.

You can change 10 to 15% of the water once every week, and clean inside and outside of the glass. If your fish produce substantial amounts of waste products, you can change half of the water. Use a hydro-vacuum every time you change the water.

Regular testing of the aquarium’s water is also recommended. Check for pH, KH, nitrites, and nitrates.

The aquarium filter should also be maintained monthly, although more frequent filter cleanings are required for a densely-populated tank.
