ER skimmer making bubbles in tank???

For some unknown reason, anytime I turn on the ER, I'm getting micro-bubbles in the tank.

1) Any ideas what is causing it?

2) Do bubbles in the tank hurt the fish or corals (mainly SPS)?

This started only after I cleaned out the collection cup. It had been running fine for months up until tonight.
