hair algae in 20gal tank

[Nsmith]

I have a 20gal tank with multiple corals and rocks and i noticed yesterday that i have hair algae on alot of my rocks, how do i get rid of it?

[bcrum51]

with alot of time and patience you most likely have high nutrient levels in you tank you need to find out why and target the source that cause the growth of the algae

the next time you do a water change you can pull the rock out with the HA and scrub it in the old tank water with a tooth brush. how long has the tank been set up? HA is a sign of to many nutrients or phosphates in the tank.

its been set up for like 3 weeks...i cheated with this tank.. how do you know if your high in nutrients? and how do you lower them?

[chrisd]

weekly water changes will help and a skimmer.
most of the time excess nutrients comes from over feeding
with a tank that is only three weeks old it has a ways to go.

i agree on scrubbing the lr i usually rinse the with new asw before placing them back in my reef.

What does cleanup crew consist of? My mexican turbo snail mowes down the hair algie , lettice slugs , emerald crabs , hermit crabs all love it ? So why scrub it ?

i have never had a turbo snail eat hair algae...I have had emeralds pick at it and my fox face eats it.
