very serious pest algae
 

Since last year, there are very horrible pest algae have been grown everywhere.

No creatures are interested in this algae. Tangs, crabs, whatever.

Could you recommend what species are enjoying this algae?

Any information or tips would be highly appreciated.

Have you tried an urchin?

It looks like dictyota. These guys have pretty strong chemicals to avoid getting eaten. Agree Urchin is least picky grazer I know of.

I really appreciated. Yesterday I put Urchin in my tank. I will show if there is a positive signal.

I agree, it looks like dictoya. Believe it or not, I have bought a prettier version of dictoya twice for my tank, but my hungry little mini strombus snails ate them before they could get established. If the urchin doesn't do it, you may want to try them. Good luck!

I have faced with the same problem in my tank. I hope it can help you ( it works for me )

- EHEIM water care Algozid
- you need to do about a 20% water change
- after 5-7 days repeat water changes

You got the iridescent blue kind? And the mini strombus ate it? Amazing/hilarious.

No, it wasn't iridescent. It was an olive color, and grew tall enough to move nicely in the current. I got it at GCE.
