I have a Tunze Nano Wavebox 6206 with controller for sale. Only 1 month of use on my saltwater aquarium. Bought it from Aquatek for 350.00 with tax on 5-29-09. Comes with everything including box and all instruction manuals. Works great producing a wave of almost 2 inches on my 75 gallon. 250.00 OBO takes it. Pictures are available upon request.
Thanks,
John
