My tank has been up for four months now and i had this problem before and then it went away for a few weeks and now it is back. What may be the cause of this. Thanks

Does your sump have baffles or live rock in it? These will cut down on micro bubbles, you might also consider adding a course types of filter foam around your return pump to further eliminate bubbles. One more thing, be sure your return plumbing is submerged. (in tank)
