Hi everyone,
In the 10 or more years I've been reefing, I've never really had an algae bloom or problem like this, so I'm not really sure what I'm dealing with here. All of my beautiful coralline covered rocks are browny, green and 'furry'

Even my snails and crabs have algae on them. I now need a clean up crew FOR my clean up crew. Haha. Its all over the glass, power heads, the algae scraper.....Basically, its EVERYWHERE.
Background info:
Its a 5 year established tank that I just moved 4 months ago
nitrite and ammonia 0 (or as close to it a possible)
phosphate .5
nitrate 20-40

temp 79
salinity .025
Good circulation with no stagnant areas
Tank looked awesome up until 3 weeks ago when i noticed high nitrates and performed a 40 percent water change
Euroreef skimmer on a very wet skim at the moment
I'm trying to make this post as short as possible so that it contains only relevant info, but PLEASE let me know if there is anything else that would be helpful.
Sorry the pictures are so bad. I took them with my phone. If better quality pics a required, I can use my bf's camera.
Thanks guys
