stupid micro bubble.

[Dustin1231]

Is there anyway to trace where the bubbles are coming into the tank there the return. Ive had the tank set up for months now, and havent had a problem. everynow and again a few bubble would come in. But now its constant bubbles...
any help would be great.

Could be an air leak. Maybe go over your plumping and look for something loose.

Do you have a filter sock or something on the return pump intake?

Also if you have a skimmer in the sump, how close is it to the return pump? Maybe cut the skimmer off and see if the bubbles stop.
