green hair algae on codium (macro algae)

[saltyfish24]

I have green hair algae on codium. This is what codium looks like. It's hard to remove the hair algae without breaking off the fingers. I've read mix info about using peroxide for green hair algae, and I was afraid since codium is a type of algae, hydrogen peroxide might hurt the codium.

What other options are there to remove the hair algae?

If you don't have any way to remove it manually then I would suggest a UV sterilizer and then an invertebrate not large enough to eat the macroalgae (snails, shrimp, etc.)

Try lighting brushing it.
Dove snails are the recommended clean up crew for macroalgae but they can be hard to come by. *DO NOT BUY LIGHTING DOVE SNAILS they are not the same and will likely not clean your macroalgae.

I had that happen to me once but I never did come up with a solution. I just kept manually removing the gha on the codium and eventually it quit growing there.

Didn't know about these snails, thanks. They look pretty cool, so that's a big plus.

I have a 1200 gallon reef tank and after 40 years and as much advice on hair algae I finally fond a solution which I want to share with everyone. A 6 inch UV bulb with a 90 degree stainless shield so as to not hurt my fish, moved around every 24 hours. I should sell this idea but love people who love the hobby, so here you go!!
