Hair algae in a 10g

[mr_alberta]

If you are looking for biological means of taking care of the algae, then a sea hair or lettuce nudibranch are your two best bets. 10G is too small for any of the algae eating fish such as tangs or rabbitfish, so you're going to have to go with inverts.

Problem with Sea Hairs or Lettuce Nudibranchs is that they release toxins when stressed or dying so, in a 10G tank, that's going to cause you problems if you're not careful.

Alternatively, since you say you are on top of your phosphates and nitrates, you can try to wait it out. Keep up with your water changes and on top of your phosphate and nitrate levels and you should see the algae receed on its own.

Lastly, adding a refugium full of Chaeto or some other Macro Algae could also help.

I added a refugium a few months ago with some red macro algae I got from Golds in calgary, not sure what kind it is.. But the macro has barely grown at all in these months and it has not done anything at all for my tank. I run a 13w light in the fuge when the main tank lights are off. Should I replace this macro with chaeto or am I doing something wrong?
