Can I eliminate their?!

[diver_ua]

There are few species of halimeda, caulerpa etc. in my display tank. They growth everywhere. Is it possible to kill them for ever?

Do you want to eliminate them? The halimeda you may be able to pull all of it out. The caulerpa can grow from a tiny fragment and may be more difficult. I dont know too much about your system bu you could try to starve it and get it to go sexual. This may require adding a better species of macro to outcompete it.

So long as your not trying to grow any other types of macro's in that tank, I'd put in a foxface and/or some large Turbo snails. The snails won't eat the halimedia, but the foxface will.
