[tunaluver]

the coraline on my overflow turned pink in one little spot and was hairy and within hours had spread all the way across the overflow and now where it had been pink and hairy it is now just white. anybody seen this before?

What have you done to the tank recently?

[tunaluver]

hadnt done anything.. just seemed to randomly appear and now is gone but that spot is now white.. started like the size of a nickel and spread in couple hours and went away

[demonsp]

Dont know but sounds like it died. If you havent check i would check all readings. Could be a sign.

everything else is fine... the rest of the coraline in the tank is fine. just that one spot
