was wondering if anyone has tried these new wavemake powerheads? But is the are too new it may be the same issue with what I have. I now have a red sea wavemaker with 4 Koralias evolutions. And if anyone has them they are a great pump if you do not mind sending for a replacement grill a few times a year. That does not sound like a bad deal since Koralia will send them to you. But like me all 4 go at once and I have to place my original Koralia in the tank until the grills show up in the mail "PINTA". Just was wondering if these would be the same problem that only time will tell.
