How to kill an anemone?

[sid700]

I don't know what kind of anemone I have, but they are starting to multiply. I use to have 3, now I have 5 that I can see. I've researched majanos, but mine doesn't look like them. How do I kill these anemones?

The tentacles are kind of wirey and mimic green hair algae. But they have mouths, move around and splits.

Why not try hitting them with kalk paste and see what happens?

kalk paste or if you wanna go natural try some pepermint shrimp.

How exactly do I apply the kalk paste? Any special technique that works well?

 

[A_Lee]

Place a little bit of kalkwasser powder into a small container, and add ro/di (while mixing) until you get a paste.
Adjust the amount of either ingredient until you get a nice viscous consistency. Use a clean pipette to test the consistency; you don't want it too runny, otherwise it will get blown away in your tank.
Turn off all your tank pumps before applying. Let the paste sit for 10-15 and siphon the area where you applied it. Be sure not to add too much at a time, because kalk will make your pH jump very quickly if added in a large enough amount. Couldn't hurt to test your pH either.
That what I did to get rid of some waving hand anthelia, and it worked like a charm. Some other people may have a different method for going about it.

Also make sure there are no coral around because the Kalk can burn them and also make sure it does not fall onto anything else.
