EDIT: Link for XP Parts... 4th post...Air in an XP2 question.
I had retired my XP2 for a few months and put a small Haggen sponge filter in my 26 gallon since its a newby Cherry shrimp tank. Then I decided to put my old trusty XP2 back in. It continuously released micro O2 bubbles. Looked like the tank was on pearl overdrive but there isn't any CO2 in that tank yet.
Somehow air was getting in the system and I feared an airlock might kill the XP so I've temporarily retired it again. So I'm wondering, since I put airtight stainless steel hose clamps on all the hoses, could it be the O-ring on cannister's top, or possibly the O-ring around the impeller? I can't figure how else air was getting into the can. There wasn't any noticeable leaking. Perhaps the O-rings dried out a bit during retirement and are no longer viable?
