Green hair algae in sump OK?

[sparkyee]

Hi,
I have alot hair algea growing in sump. It is
covering the caulerpa with this thick green gunk.
The tank has no hair algae at all except for behind overflow. I am lighting the sump with a 27 watt LOA on about 14 hours reversed from the tank. The caulerpa is separated by aperforated pvc sheet. Lots of pods in gunk. Should I just
leave it or is it a nitrate trap?
Thanks for any response!

Well, it is a nitrate trap and, as such, you could remove it, thereby exporting bound nutrients from your system. When I overfeed I occasionally get a hair algae growth in my refugium (or cyanobactre). I then remove it and it doesn't re-grow until my next bout with undisciplined feeding. I'm actually very talented at turning food into hair algae. Unfortunately, there is no commercial demand for my skill.

my opinion is let it grow and perodically remove part of it which will export nutrients. if it is growing good in the sump, it is maybe taking nutrients out of the water and therefore the algea cant thrive as well in the main tank.

just my opinion

I agree. The only problems w/ micro algae in the main tank is covering corals and how it looks. it is a nutrient trap.

No problem letting it grow in the sump. Remove it occasionally to export nutrients, but better it grows in the sump than in the tank, right? Plus, various pods seem to like (and reproduce in) thick beds of hair algae.
