oK, so i have an odyssea protein skimmer not the best but does the job - it has worked well for awhile, i changed some things around and cleaned the skimmer and when i turned it back on it fills the tanks with small bubbles and i cant get it to stop. Im thinking if i run it for awhile it will be ok, but i wasnt sure if the bubbles would hurt the fish or corals etc. any ideas what the problem may be.
