I have a 12g Eclipse. In the past few days a brownish and stringy algae has begun to grow on the rocks. I have attached a picture hoping someone could tell me what it is and what I should do about it. The tank has been running about 6 months and routine tests are OK. Thanks in advance for any insight and help.
