The aquarium pump is the most important part of your aquarium. They remove water from your tank, pass it through a number of different levels of filter media, and return filtered, oxygenated water back to the aquarium.
Without an aquarium pump, two problems arise: first, the water in your aquarium becomes cloudy and dirty, and algae and bacteria attack every organism – a sure death for your fish! You can also get more info here about various fish tank pumps.
The second result is that without an aquarium pump, the oxygen in the water decreases over time and your fish will no longer be able to filter it through the gills – your fish will have a hard time here too!
However, the installation of a fish water pump and filter system is essential. There are three things to keep in mind when purchasing a system:
Is the system compatible with your aquarium? – In some situations, the system may require a connection that is not available in your aquarium, or the pump itself may be so large that it cannot fit where you want it to. Make sure you know the dimensions before buying a pump.
How many gallons of water should the pump run? – Small pumps can be used in large aquariums, but may not provide enough oxygen for all of your fish. Additionally, the filtering system may not filter water sufficiently to keep the aquarium free of harmful bacteria and algae.
If you are unsure about your pump requirements, contact a specialist. By answering these questions, you can decide which example of all aquarium pumps is suitable for your aquarium.
