Wavemakers are designed to simulate the wave of motion of the natural habitat in which your animals live. There are many benefits that a wavemaker provides to your aquarium. The current and movement which a wavemaker provides will help to eliminate build up of unwanted waste which can be harmful to your corals. This action will stir up the aquarium water allowing the water to be filtered through your system catching the debris. Corals need motion in the water to survive, lack of water motion can cause the animals to smother and die off. The movement of the water helps to bring them the nutrients they need from particles in the sand and keep them healthy. Fish also like water movement; they challenge the current therefore making them feel at home. We recommend a wavemaker accompanied with powerheads to simulate the natural healthy habitat your fish and corals come from.
