Tiny bubbles coming from my filter clouding my water.

[heerism]

I have an Emperor 400 Hang on Back filter for my 40G saltwater tank. I have the water level as high as it goes in the tank but when the water comes down into the tank thousands of tiny little bubbles are being created and just cruising all around my tank. Any suggestions?

Bubbles are usually a result of a small leak in your plumbing, allowing air to enter the waterstream. If yours only show up after evaporation, then check joints just below normal water level.

I have the same problem w/ my Emporer and a 55g tank. I don't think it has anything to do w/ plumbing since there really isn't any plumbing involved.
I just figured it might be helping to add oxygen to the water, so I've ignoted it.

I have the same emperor 400 and I do not get any bubbles. I would check it out before I decided to live with it.
