Green Algae

[tanyamikephil]

We have suddenly got green algae growing around the tank. Some of it is interfering with things like the zoanthids which it is growing over.

How do we deal with this issue?

Thanks in advance for any input.

a close up pic of the algae would be better to id. if it's just green hair algae, i'd remove the algae manually and lower the nitrate and phosphate. water changes, skimming, algae scrubber, gfo, etc will all help.
