I have a used KH Director with the standalone 2.1 Doser that I brought from a fellow member about year ago. Its works great but I recently switch to the Apex trident and have no use for it anymore. I'll include the magnetic stirrer ,extra tubing , ph calibration fluids. I recently changed the pump rollers and tubing . I don't have the reagent fluid for the director which you need to get . For Sale $550
