I have 2 Maxspect Gyre XF230 pumps with the advanced controller that I am looking to sell. The pumps are in like new condition with all the original packaging and extra pump heads. The only defect is on the controller screen. When you program the% of flow it is blurry in that section of the screen but when done it is clear. I talked to CoralVue and they said that they would replace it but at this point I will leave that up to the next owner. It does not affect the function of the pump and you really don't mess with programming much with these pumps. I am asking for $350 shipped or trade for a MP40QD newer.
