Roger,
Is it common for the impellers on these skimmer pumps to swell and split like this? It's been in service for a year, and wasn't like this when I cleaned it six months ago. I had noticed a decrease in performance of the skimmer, and this is likely the culprit. I had this issue on an old Euroreef that the 9430 replaced and had to replace the impeller every year like clockwork. The skimmer has otherwise performed like a champ so far....
