i would like to buy a Needle wheel impellar pump (250gph) to replace my sendra ksp-2500, that runs my ASM-G1 skimmer. its gotten to the point of not starting back up when the power is cut during coral feeding. I might just need the needle wheel impellar but thought id see if there where any skimmer pumps around for a decent price. I dont want to spend $20 on a new impellar just to find out that the pump is also malfunctioning. So if you got one layin around, Holla!
