they have one used at Tropical Island Aquarium in Deer Park for $40 I think. You might want to ask if they've ever used copper or other chemicals with it though.
Great store too, so even if the tank doesn't pan out, the corals and fish are worth the trip
no problem. I live in Mineola. I think you bought a powerhead from me a while ago. IMO Tropical Island is one of the best stores to hit on a regular basis.
