I have sold my tank (120 gallon) and livestock and have no further use for it. It has been used for about 3 years. It is rated for up to 300 gallons. I have retro'd it with a Precision Marine injector, which I believe are better quality than the originals. I have 2 additional MRC injectors for a total of 3 injectors - skimmer is capable of running 2 at same time. I am also including a Blueline 55 external pump that drives it nicely. Total for everything $200. Pictures will follow. Thanks...
