I've had my 65gal reef tank for 3 months now. my protein skimmer has stopped producing pulsating bubbles and thus it is not doing any skimming. The pump works, the mini air bubbles are firing in the chamber just like they did for the first 2 1/2 months while it was producing protein. Is it possible my pump is worn out? Do I need more air? Could my water just be clean enough to where there is no extra protein. This has been going on for a little over a week now. How would I know when it's time for a new one? Thanks!
