Hi everyone, MP-40QD for sale $290 shipped and all PayPal fees. Mfg date 08/15. Used for about 7 1/2 months in Tidal at 35% and lagoon at 25%. My current system is small and this is too much for it. It has one of the protector lines of the impeller in the wet side missing. Too much cleaning but does not affect the performance. Thanks.
