But now there is a simple answer to that. The HYDOR rotating water deflector. It is supplied with proper adaptors so fitting it to the outlet of almost any pump or filter is possible. Its clever design means it moves slowly and silently without needing any power source of its own. It moves the aquarium water in varying directions which in turn increases oxygenation and greatly increase surface gas exchange, preventing the formation of the “white line” effects. Watch the video below to see how simple it is and the effects it will have on offering varying flows across your corals which will greatly increase their eating and overall well being due to the wave effect.
