Anyone know if there is a replacement impeller for the Skimz Eden ES2800 pump? Found this during a routine check on a tank I'm setting up. Good thing it's just cycling and nothing in there yet. $100 for just an impeller is a little steep. Had to pony up for Bubble King parts in the past because of shipping from Germany but thought Skimz would be a little more on the poor man (like me) side.
