what is bga??

 

[doresy]

Blue green algae maybe? Releases toxin, fish wont eat it, no real cure. One to be avoided!

or it could be something completely different

yup BGA is blue green algae, however it is a misnomer as BGA is actually a form of cynobacteria.
it can be cured by serveral methods, treating with a fish antibiotic, like acriflavin or placing a copper coin in your filter
(many despise this method due to the dangers to other aquatic life)

you can also try a black out as somtimes this works to get rid of it
