Hair algae on cheato

[whatcaneyedo]

I've had this happen recently. I observed it for a long time waiting for the chaeto to outgrow the hair algae. After several weeks I gave up and just pulled most of my chaeto ball apart, threw out what had hair algae on it and dumped the rest back into my fuge. Its been fine since then.

If you dont have very much maybe consider throwing all of it out and getting a new fist full of chaeto off of someone in the area.
