I have a barely used WaterGeneral RO/DI System, model #RD-100. This link is a close approximation, but with only one resin housing, not two. Comes with a half-full bag of resin and the resin in the housing has only been used to
filter about 20 gallons. So, it is essentially brand new, too!

Retails for about $150, I will sell for $100. OR, I am also looking to upgrade my lighting for my tank, I have a 30 gallon 30" tank and my light is only 24" and fairly weak. Would like high-output or metal halide setup, preferably with blue LED's and/or dawn-to-dusk capability. Am willing to do a trade (with me paying you in cash along with the RO/DI, obviously), used is better so I can afford it.
Will also throw in a medium piece of dry rock if you are looking for more for your set-up. If anyone is interested, drop me a line or just reply!
