help with cynobacteria

[reefmutt1]

I have a 55 with 20 gal sump below and a 10 gal refugium above. I am trying to grow feather calupera in the refugium but it seems the cyno bacteria is chocking it out . I have a lil cyno in the main tank but i can control it its the refugium that is out of hand. Any suggesstions?? Ive tried increasing current flow and removing it by hand with litlle avail....

Cyano....blue or red? Anyway, what needs to happen is an increase in circulation, decrease in feedings, and reduced photoperiod

If your lamps are aged replace them. Run carbon for three days then discard

Some of the cyano can be removed by hand. HTH
