My sicce syncra sk400 stock pump for my vertex omega 150 keeps stalling during start up its about 4 months old, did vinegar wash.... tired of it before I take hammer to it and smash it what impeller would work better on it or what pump can I replace it with, thanks in advance. P.s. Skimmer sits alone in its own chamber there's no other pumps around it.

excellent Skimmer pumps not the best.
