Aquarium Water Pumps – Essential To Aquatic Plant Success

Water circulation is essential in any aquarium to ensure proper filtering, prevent the formation of anoxic or low-temperature areas, and add nutrients to immobile organisms. The drive heads and aerators often ensure adequate blood flow in the main aquarium.

However, in a planted aquarium, the water level should be kept as undisturbed as possible to prevent the loss of valuable carbon dioxide, and such devices should not be used.

The water pump ensures the necessary circulation both in the tank and through the filter system without unnecessary gas exchange. You can also buy filter roller online via

Choosing a water pump is one of the most important tasks to ensure a successful experience. Several criteria must be considered:

1) Flow: Water pump flow is estimated in gallons per hour (gph) under free-flow conditions. For example, a 100 gph pump circulates all of the water in a 50-gallon tank twice an hour. The presence of a filter (and its condition) will reduce the actual flow. It is important to choose a pump with sufficient flow to ensure proper filtration.

2) Durability: The water pump is one of the few devices with moving parts in the aquarium and therefore subject to wear. Some pumps (e.g. magnetic drive) are designed without corrosive internal seals. This is more important for a saltwater tank, but it is necessary to consider a planted aquarium.

3) Heat Generation: The electric motor generates heat which is released into the water. Too much heat can cause unwanted wear and tear if you need to keep the water temperature below a certain level.

In general, you should choose the best quality pump that you can afford. There are fewer causes for headaches in an aquarium, worse than a bad pump: noise, overheating, and leaks at the worst possible time can drive you to make a change.
