Well, if anyone is interested in it, I have one up for grabs. It is still being run on my tank, in good working condition. It comes with a pump and tubing. I would take a pic of it, but it is kinda hidden at the moment. Made by aquauv, it is actually rated for a pond, to clean those up, but works nicely for any aquarium. It has kept my fish disease free. BUT, i could use the money, will take best offer. The pump is via aqua, low power so as to let the water flow through slower, thus exposing it to the light for longer. I live in CT. I can ship, but you pay for shipping. Thanx.
