I do see black brush algae on some of the plant leaves [the brown fuzz mentioned in the post above], in addition to what I will accept is hair algae. It really does not matter what type (species) of problem algae it is, because the cause is the same for all of them, as is the cure.
It has to do with the balance of light and nutrients, nothing else.
The light here is likely too strong or too long in duration. And something to keep in mind...these LED light systems which give you options like dawn and dusk can be encouraging problem algae. This is because the light intensity is not sufficient to drive photosynthesis (it presumably is adequate during the "daylight" of brightest light) but algae doesn.t care and it will take any advantage, so this lower lighting is actually benefiting the algae.
Floating plants once again are a saviour with problem algae. Assuming the balance is not too far out, just having a decent number of floating plants can not only provide less light to the lower plants (avoiding problem algae, hopefully) but the floaters use a lot of nutrients and this helps to reduce the benefit to algae.
