ULNS algae issue

[authentic]

I run a ulns sps tank ,nitrates .25 phosphates 4 Hannah checker
I have a green algae on my rock work that I can't seem to get rid of,most of it blows off but some remains on rocks and grows back,not hair algae.have added more cuc but I'd like some ideas.running 2 wav powerheads at about 80% max, the rest of the tank is doing great,good color and growth alk at 8-8.5

It looks like your numbers are backwards. Shoot for Phosphate 0.02 (Hanna ULR) and Nitrate 5

Sorry nitrates rested at 2 phosphates at .10

.10ppm po4 is plenty for algae to grow. Instead you need 0ppm for weeks at a time.

Cut dosing or supplements of any food or Amino Acids for corals and try lowering you phosphate to 0.03
