I have this algae growing on a lot of my bromeliads and also some of the branches in my vivarium, and would like to know if it is cyanobacteria, if not any ideas as to what it could be? Also the best remedial action to take?

A few details about the vivarim itself :
30 x 12 x 18" vert tank
Lit by a Grobeam 1000ND LED tile (containing 10 x 6500k CREE XP-E LEDs)
Photoperiod of 13 hours (Including 1 hour combined of sunrise and sunset provided by the controller)
Misting 2 x 30 seconds per day, early morning and late evening (4 Mistking Nozzles)
Internal air circulation provided by a 60mm fan running at 7.5v
The only thing I can think of is stagnant air (hence adding a small fan a few days ago) and / or the use of bottled mineral water (high nutrient content for the algae to thrive off?)
I hope you can help as its very unsightly and is vexing me
Regards
Anthony
