Bryopsis, derbesia... Gha, cyano.. All not cool!
All nutrient related, so lets tackle that.
When you measure po4, are you using a test kit? Find someone that has a photometer / hanna / milwaukee low range checker.
Even if that measures 0, you could be dealing with substrate / rock bound nutrients.
Have you removed your bioballs from your overflow weir?
How much do you feed and what?
Fish bioload?
 
Irie if lights are on for 2 long could this not be a cause to aggravate the growth? I agree nutrients are most likely a cause. Does the tank have sufficient flow?

Remember sometimes your phosphate will read as 0 on test kit as the phosphate is being used up by the algae.
 
Leave it you tank is still going threw a mature stage if your parameters is good like yours then yes just leave it it will go away ratchet get yourself a algae eater fish like a salaris or fox fase
 
If you have too many blue lights and not enough white lights could that not give you an alge problem ???

Normally the other way around. But algae is more a nutrient problem than a light one. If your tank has too many nutrients, nuisance algae isnt too fussy as to what lights it needs.
 
Had the same problem, id not worry about it too much.. Tank still cycling..
 
Agree with the previous posts, I would double check that there isn't any kind of dead growth on any of the rocks, like a dying sponge or something, just incase something like that might be leaching nutrients into the system. Otherwise I would get one of those big turbo snails (Saltwater Aquarium Snails for Marine Aquariums: Turbo Snail ) (even if you only keep him for a short period of time until the system balances - because he might run out of algae to eat) or a algae eating blenny of some kind.
