A couple more suggestions.

An issue commonly encountered is a change in the viscosity of the water. Many of the water conditioners, bacterial supplements, medications, coral foods and greasy fish food will increase the viscosity of the water significantly. If the 'greasiness" is not removed through water changes and running activated carbon, the viscosity of the water would increase and there would be more foaming and microbubbles.

It would also be a good idea to check the pump, impeller and air intake parts to make sure everything is clean. If the airflow is restricted, the pump would draw in more water which causes water and air bubbles to travel through the skimmer quicker than it normally would. This causes more microbubbles to exit the skimmer as it has less time to dissipate.
