Fine bubbles in sump tank

[Michael]

I am using BM curve 5.5 in sump. After first cleaning if skimmer, fine bubbles appeared in sump and goes to the display tank. Prior to this, I do not have this problem. Any advice on cause for this fine bubbles. I tuned the skimmer in the skimmer chamber. If it's fine bubbles in chamber then it seems to have phenomenon.

Just put some filter wool before your return pump should help in preventing the fine bubbles from going to your display.
