I am looking at used precision marine bullet 2 protein skimmer. What replacement pump should I look at. This would be my first skimmer and I am not sure what pumps are good. If I can find good used equipment to make my build cheaper I can use those funds for other goodies. I am ok with old components that have new moving parts...they usually wear out, pumps break in time. I know some areas should not be cheap because they tend to bite you, pay me now or pay me later. Bad decisions make great stories. I would rather ask and learn from those who are more knowledgeable than myself. This unit is going into a 90 gallon system. Thanks for your help.
