Okay, I finally rigged the new Euro-Reef
skimmer up so that bubbles aren't dumping everywhere in the main tank. It's getting adjusted, and seems to do a great job. Here's the dig: the vibration noise is unbearable! I can't even pinpoint it. If I turn off the pump to the
skimmer, it stops. If I turn off the pump back to the main tank, it stops. Both run, it's a distractingly loud deep humming sound. Any ideas?
