Merry Christmas to everyone. I have spent the last couple days getting my Gyre xf250 up and running. I was skeptical about buying this but was tired of the "Powerhead Clutter" in my tank. So far the Gyre works really well, I have it on random pulse and have flow all over my tank. My max output so far is 50% very quickly at the peak of the random cycle, the rest of the speed is 10 - 30% output.
Cheers to all,
Rick
