The everyday requirements for the care of your fish are not much. But do observe your aquarium inhabitants everyday to make sure they are cheerful and look healthy. You will find that fish that are emotionally disturbed will fall sick often and mental ill health is a cause of physical ill health in fish. The lights and filters are important to maintain the perfect equilibrium of the aquarium so do check them regularly to make sure they perform in peak working conditions. The necessity to feed them daily cannot be undermined. Only feed what can be consumed in the first two to five minutes. All food left over after the fish have consumed what they have to will account for waste debris in the tank and will pollute it by adding to the nitrite levels which will cause the fish to become sick. Perform a pH test every week to see if the water´s pH level is still good. It is a big mistake to delay making any changes where necessary. When you are buying your fish from your pet store, ask them what levels will be suitable. Every variety of fish can thrive in particular conditions.

The filters will eventually fill with debris and be unable to do their job unless they are cleaned. In addition to removing the waste debris from the tank, some filters can also provide a circulation of oxygen into the tank. If the filters are clogged, circulation slows. This tampers with the oxygen supply in the aquarium. If left untreated, this could be deadly for your fish. You have to assess the need of the aquarium and accordingly change the filter once every couple of weeks. You will know when it needs to be cleaned because the water will become cloudy or smelly. There are two things you can do with your filter depending on its design you will either have to clean it with water or you will have to change to a new one.

The proper way to change water in a tank is to do it gradually. Before cleaning your aquarium, make sure to unplug all lights and other fixtures. Change only about one in three parts of the water of the fish tank on a weekly or biweekly basis. If you are adding tap water, you may need to treat it before putting it into the aquarium. The retailer at the pet store will guide you on the proper kind of water to be used. Some treatments allow the tap water to be ready in as little as an hour, while others need to sit overnight before being added to the tank.

Shift the rocks and other nonliving stuff in the aquarium to release debris held under them. When replacing the water, try to get this debris out using a small bucket or a vacuum siphon. Remove all dead leaves from the water plants. Use a squeegee soaked in clean water to clean the outer surface of the aquarium. Clean also the lid and the cover of the aquarium. Plug everything back into the aquarium, sit back and take the pleasure of your newly cleaned aquarium.
