Well figure this one out? I have beeen using a refugium with a built in skimmer ,no problem works great. Up till now. Had a red algae problem i got some med from the salt water store.Read the directions. Says to turn off the skimmer, and take out any charcoal you may have. No problem. Put in the med ,a white powerdy substance. Waited 48 hours. Did a 30% water change like the directions said. Cleared up the red algea. Waited another 48 hours,like it said then opened the air for the skimmer pump and got millions of small bubbles pumping into the aquarium from the return hose.When i turn off the skimmer no bubbles at all.I have tried for the last 5 days to turn on the skimmer and still get millions of mini bubbles.skimmer worked fine before i put in the med. Any suggestions????
