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.

REVIEW
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.

REVIEW
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
