I have a Hydor Wavemaker, nano 240 and 3 nano 565 powerheads. One of the 565 is just a few months old, one is about a year and the other around 2. The older 2 565s have new cages. All were working great when i pulled them for nero 3s. They were great in my 25 peninsula. I am selling them all for $100 local/$120 shipped.
