Bright green hair algae, can't get rid of!

[robbyville]

Hi all,

I'm having quite the problem with bright green hair algae. Especially around my zoos, and pink birdsnest. Does anyone have any ideas as to the best way to scrub the algae off?

I have scrubbed and removed, done multiple water changes over the past few months, I'm not over feeding, I am using RO/DI water. I can't seem to figure out why I am having these problems?

Any ideas as to what I can do, or test for?

Thanks!

Rob
