Algae From Hell

[Akerfeldt]

I can't seem to figure out how to get rid of this algae. I've never seen this kind in my years of reefing. I started noticing it after dosing rotifers and amino acids together. After a couple of weeks, I got a large cyano bloom along with this brown stringy stuff. Since then, the cyano has subsided (not completely gone, but getting there), but the stringy stuff continues to grow. I don't mind a little algae, but it's beginning to grow on my sps (causing them to stn), and I've even lost a colony of Rose Nebula zoas (100+) because of this stuff.

I currently run a 60G tank. I have lots of GFO (combination of Phosar/Rowa), a decent refugium, and a decent skimmer (NW150 meshmodded/maxed out... soon to be MSX160).

I've tried doubling the dosage of GFO, dosing sugar/vodka, more frequent water changes, etc. etc., but the algae keeps growing?

SG - 1.025
Alk - 8
NO3 - .2

I also have plenty of flow w/ 4 Tunze 6045's modded.

Thank you so much. They're definitely dinos. My snails have been dying left and right because of this stuff.

I read through the link... any tips on how to go about dealing with these guys? I figure I'll keep my fuge light on during the night to keep my pH a bit higher, and drop by tank lighting down to 4 hrs.

This stuff is really a nightmare, I can't believe how frustrating this is....
