Ocean Currents Rocks!
I run Oscillators on both of my tanks and also had an old one(3ish years) that was dead. Then Oscillator on the 90 died. I e-mailed Ocean Currents and they offered to fix for free my newer Oscillator and also my old one. I just got both of them back today and they are looking great and working like a charm. They do not seem to last as long as I would like but from what I hear there is a new design on the way. And with their willingness to stand behind their product I have very little to complain about.
