Help - air bubbles question

[scubaj]

I just setup a 120g with a sealife reefmaster pro (with fuge) sump. I have a mag7 and rio2100 submersed pumps as returns and a rio3100 submersed pump feeding my external Aquac ev180 protein skimmer. No matter how I arrange the pumps, I can't eliminate tiny air bubbles - mostly maintained to the top 1/3 of the aquarium but the Vortech 40 that I have is moving some lower. My LFS tells me this is normal?? Will this harm my fish, inverts or corals?
Thanks!

A normal problem.
The big thing is at the surface the bubbles brake and spray saltwater mist caking everything with salt creep. The salt creep is bad for most things above the tank and if it falls back into the tank it can burn tank inhabitances.
Post some pic’s of the problem area.

i have the same problem, i used a filter sock on the end of the piping that goes into the sump, cuts out a lot of the micro bubbles going into the sump, it hasnt cut it out completly but it did help out a bunch, im still trying to solve this problem myself, i will be tagging along with this one.
