Red Algae

[merlberg]

I have this burgandy looking algae all over my tank and it has gotten worse over the past few months. Can anyone tell me whats going on with my tank please?

Cyanobacteria. It proliferates when their are excess nutrients. There are treatments available to deal with it.

Looks like cyanobacteria, not really an algae. Suck it up and check water conditions. Also might want to increase flow in areas it is growing if possible.

Thanks guys! Will it harm any of my fish?

Not harmful, just ugly.
