How to combat hair algae?

[scholar]

I have Foxtail and duck-week which I thought would not let hair-algae to compete. What conditions let Hair-algae to compete?

Secondly what fish/snail/shrimps would eat hair algae?

Thanks, :)

PS: I have five tanks and this is the only one with Hair algae infestation.

Mollies, Flagfish and Rosy barbs seem to enjoy hair algae. :)

I just put 2 Flag Fish in my tank about a week and 1/2 ago had hair algae bad. It's all gone along with other algae that formed on my plants.

also remove what you can manually and lighten up on the iron dosing.

I just reduced my lighting to 1wpg and did a blackout...some say this doesnt work...I also cut my furts down to once a week...its gone because I'm still doing 1wpg
