Green Hair Algae - Will not go away!

[Pinchy]

Hey there,

I need your help.... It has been a few months since i have posted on here as i have been frusterated battling a GHA outbreak after taking down my sump / refugium on my 75 Gallon Reef after a mini flood scare. Since removing my sump i have added a Fluval FX5 with live rock, bio pellets and carbon. I also have an Aqua C Remora Pro HOB skimmer. I am also currently up to dosing 3.5ml of vodka every day. My lighting consists of two LED EShine Cree Pro's (6 months old) and circulation consists of a Vortech MP40. I have been testing my N's and P's and they read as follows:

N: >10
P: Undetectable

My sps polyps are out, and everything seems to be doing fine, but the GHA is growing out of control.

My lights are on for 7 hours a day with one hour on each side of just the blue acintics running, for a total of 9 hours.

I have added a sea hare (it died) i have added turbo snails (they died) but my starfish and other invertabrates seem to be doing fine.

I also have a diamond goby keeping the sand bed nice and stirred up

I have tried everything from scrubbing the rocks with a toothbrush to ripping it off with my fingers and it still wont go away. I currently do two water changes a week and the results are futile.

Please tell me what i am missing!?
