Algae

[rontheking9905]

Algae drives me mad!
I can see I have some green spot but what do you think the black stuff is.
Is it just an excessive amount of green spot or something else?
I have had BBA in the past but this doesn’t look as furry as that.
Any help is appreciated

The black stuff on the Anubias looks like blue green algae (Cyanobacter bacteria). It loves light, nutrients, low oxygen levels and calm water but can grow just about anywhere. Cleaning the tank up (big daily water changes and gravel cleans for a week, and cleaning the filter) usually help. Reducing dry food and increasing aeration and water movement can help.

The brown stuff on the wood could be a variety of beard algae. You can try taking the wood outside and hosing it off.
