I can't tell because of the blueness of the image, but it may be cyanobacteria, not algae, and nothing to do with phosphate. If it is red, either red dust or red sheet, and especially if it has air bubbles, it's cyanobacteria, which is treated by turning out the lights 3 days a month (one day of blue light only, after the 3 day lights-out) and letting the skimmer handle the dead stuff. You have to do this for several months in a row to really get rid of it: it will try to come back, but persistence usually wins.

If it is brown instead of red it may be diatoms, or dinoflagellates (look those two up on the internet) The treatment is usually to feed less and skim more, but it is complex. You would do better to read a variety of methods of dealing with them.
