Works great with Hydor Koralia pumps, no problems so far. I use the 3 minutes scale for alternating flow. Highly recomended

This is a very simple and easy to use wavemaker. Running for 2 months with 0 problems. I probably could have gotten away with the smaller version, but this way I can run more pumps! Would totally recommend!

The Ocean Pulse wavemaker, I got the double outlet for my 65 gallon (36x18) reef aquarium connected to two maxi jet 400 circulation pumps works as described in the description. It is mountable inside the aquarium stand.

Rated 5 out of 5 by gerryo This product is more useful than I thought.
When I got my 28G Nano Cube it came with one of these things as part of it's equipment. But I never used it. I just adjusted it so that both pumps were on at the same time.
Since then I have realised the need for lots of movement in the water so I ordered another Duo. This will be used to control 2 Nano powerheads for additional movement and to add some linear flow around different areas of the tank. Especially behind the rock.
