ReeferChick85:
A few questions:
What size tank are we talking about?
How long has the tank been set up?
What makes up your current bio-load/stocking of the set up?
Fast forward thinking: My opinion... *2 pennies*
It sounds like you're on the right track of limiting a few things here and there. GREAT.
In your case, you have started running phosphate media. GREAT.
And you're checking your water parameters...AWESOME.
Suggestion: Research the web and first identify the algae, find out what makes it thrive and cut off it's food source.
My Experince: In the past I have had hair algae blooms but that may have something to do with the 9 fish in my 24 gallon nanocube.
Here's what I did: Manually remove the larger patches of hair algae run both carbon and phosphate media...water changes...photo period shortages...feeding control...increased waterflow...eliminated 5 fish and purchased 5 - 6 turbo snails to rid my 24 nano of the rest. I agree with aquariumclown 100%.
Good luck and keep us posted on your progess.
Thank you for this!
Tank:24G AP
Setup: Over a year and a half
Bioload/Stocking: Sixline Wrasse,Yellow Coris Wrasse,Green/blue chromis,Cleaner shrimp,2 snails,some hermit crabs,nassarius snails and the typical bristle worms and serpent stars that live in the live rock.
Corals: Mainly LPS,some palys/zoas,and a couple softies.
I have never had an issue with hairy algae before up until a few months ago. I was even feeding twice a day and no outbreak like this. I know it had something to do with the water I used during a water change I did but after I realized that I did another water change. Made sure the TDS read 0 and all that other good stuff. The membranes were even changed.I even tried using a different salt mix just to see if it made a difference. So after numerous water changes and trying things out,my problem is still here

I don't feed my fish or coral as much either even tho they look hungry
I have actually tried manually removing the hairy algae from the back wall when I do my water change by using a scraper and having the tube siphon it out right away to try to avoid it from spreading but no luck. It came back.
I have researched soo much on the web for the type of algae I have and from what I've read it's all nutrient based. I know I have hairy green algae for sure,some brown hairy algae,i think bryopsis too,red and green bubble algae. I will post some pics of what I have. Maybe someone can see if I labeled them right. Sorry pics were taken with a camera phone so the quality isn't all that
This stuff looks more stringy/leafy...bryopsis?
Red and green hairy stuff on this frag plug plus on the side of my scoly skeleton as well. It's a lot shorter as far as in the length.
This thing grew suddenly.This is the only one I have of this in my tank
