Why do I need a wavemaker?

Aquarium wavemaker or, circulation pumps, are designed to eliminate "dead spots" in your aquarium fish tank. This is very important if you are keeping a marine aquarium tank or marine coral - the waste that they produce during respiration needs to be carried away from the tissue and to your filtration system.

Lack of water circulation can cause the coral to suffocate, while unidirectional current can cause the coral to become irritated and thus, to close up. Many of the invertebrates that we maintain in the reef aquarium are dependant on relatively strong water currents.

If the water movement is minimal to none, then organic substances, matter, and uneaten food can accumulate and encourage the growth of pathogenic bacteria. 
Wavemakers help to eliminate these problems and enhance the health and growth of your tank inhabitants. They are also essential for creating an environment similar to their natural habitat.
