I am currently using 2 Koralia 4 powerheads and will be adding another Koralia 1. I have been considering replacing these with the Red Sea WaveMaster Pro / Maxijet Powerhead Package - Deluxe with 4-MaxiJet 1200 Powerheads. However, in doing a little research on these I have seen alot of them used for sale on other forums. Is there something wrong with them that people don't want them. Is anyone using this wavemaker or is there something else I should be considering.
