I have a Pro Clear Pro 150 Wet / Dry and I can't seem to get the protein skimmer to produce enough bubbles to work.
It has worked sporadically in the past. I called the manufacturer who instructed me to soak the nozzle that attaches to the pump at the bottom of the protein skimmer's cylinder in vinegar. I soaked it, ran pipe cleaners through the nozzles, cleaned the pump, etc., but the protein skimmer still won't bubble up refuse and the manufacturer is out of ideas. I have of course played with the air valve to ensure it is all the way open.
It produces some bubbles as you can see in the pictures below, but not enough to bubble up the chamber. skim1.jpg
Here it is bubbling with the top off. With the top on it would have to bubble up about 6 more inches to make it out of the chamber and it never gets much higher than you see here. skim2.jpg
The pump attached to the protein skimmer is nearly 4 years old now. Could it be that it no longer has enough power to produce enough bubbles to cause the chamber to bubble up? Might a new pump resolve the issue?
Thanks so much for your help!
