Q
will these work with a wavemaker?
I have a red sea wavemaker pro I have read that these break in about 6 months because of the on/off cycle

A
With proper maintenance they should definitely last. The On/Off can take a toll on the pump, but it should last longer than 6 months.

“Great Product”
5.0

I must say these are by far some of most popular and widely used aquarium circulation pumps used in this hobby by beginnners, and experienced hobbyists.

“Hydor Koralia Powerhead”
5.0

I purchased two of these for my 90g SW Tank and they are working great. If you don't need anything fancy like being able to control the speed should you plan on purchasing a Tank Controller later on down the road. Then I highly recommend purchasing these Hydor Koralia

“Good flow”
5.0

Added good flow to my tank for a fraction of what I could have spent. After adding an extra Hydor powerhead to my current set up my zoas opened up more and previous dead spots in the tank were eliminated. Everything in the tank seems to be enjoying the increased flow. I would love to eventually add ...Read More
