I had one like this years ago. I had been looking for it and found it. Cheap great way to get wave like motion in the tank without shelling out $200 plus . Like the extra outlets too! Will.hang it soon just trying to get the right amount of wave motion. Fish and corals love it.they love swimming in the currents
The natural wave timer has helped to create an awesome environment for my corals and fish. It allows me to control flow rates at my convenience and help to disperse food, nutrients and gunk throughout the tank. Great buy!
