dang it Troy,very interesting reading,I wish I'd found this thread sooner.....I've been fighting this nasty crap for over 3 weeks now,vacuuming several times a day,3 days with lights out 3 different times,replacing filter sock every day,reduced feeding,and increased flow.....
it's finally going away,prolly just burning itself out now though....seems like every 5 or 6 months I go through this but it was worse this time than it's ever been :( I thought it was cyano but it looks more like this pic

I'm running GFO and I've been dosing vodka again but after reading this thread,I'm gonna quit with the vodka until this is completely gone......my phosphates are undetectable and nitrates are extremely low,what's feeding this stuff to keep it growing ?
if it's not cleared completely up in the next few days,I'm gonna try dosing H2O2,and I may do it anyway just for the heck of it LOL.....
I am curious if anybody with macro algae,that's tried this,has seen any ill effects on their macro algae,or more specifically,on chaeto...I don't want to kill my chaeto :D
