Hi, I was wondering if anyone has herd anything about the Hydor Koralia powerheads? Is anyone using them? Does anyone know if they are safe to be run with wavemakers? They seem like decent powerheads, they are reasonably priced, and they seem like they would make a stream instead of the jet that most powerheads make. Here's a link to them on the Dr. Foster and Smith website:
