I have been using the vertex 180i skinner in my reef for 7 years now and it’s a beast. The pump I believe is starting to die. I have cleaned it multiple times and sometimes it sticks closed and I’ll have to mess around with it to work. Basically if I shut it off it can give me a headache to get going. There is nothing visably wrong so I am just assuming age. Ideally I would like to just buy a new impeller or replacement pump but vertex went out of business. They have a custom built sicce pump that sits inside to power the skimmer. Does anyone have a replacement pump for this by any chance or a spare impeller?? If not I will have to start thinking about a new skimmer, what is everyone using for a skimmer now a days. 100 gallon reef, LPS and SPS. Thanks!
