Up for sale is my Tunze 6101 powerhead. It comes with the other magnet so you can position it where ever you would like it in your tank. It also has a small control box with a dial on it where you can dial it from 660 gal/h to 3170 gal/h. This baby can move some water. Very clean and works great. Any questions please pm me. Asking $100 for everything you see below.
