I have a Tunze 7400 (4000 l/h) that needs a driver. Aquatek quoted me $75, maybe you can find it cheaper...I don't know. Unit has about 2 years of use and should be super-clean
thanks to Bruce. The pump also comes with the single controller, light sensor, mount with
suction cup, and owner manuals for both pump and controller. New, this setup cost over $300.

All I want is either a new Koralia 3, or $50.
