Is it time for combat?

I am afraid about what I am going to hear about the first 2 pics, but not sure about pic 3.

 

Pics 1 & 2 are aiptasia.

The other is majano.

Here is what I would do.

I'd take the rocks out of the tank if possible and cover all the infected areas with Kalk. Everytime I've messed with in tank control I've only spread them. Especially the aip's.

 

Thanks for the tip, I was afraid that's what they are, so far I only seen 3 of them, quite big to, so it should be easy to kill them, are far as that majano, do I need to rid them also? there sure is a lot of those.

 

Majano! ohhh brother! WWWAAAAAA!!

 

I have to act fast, thank god I have no Coral or fish right now, how about if I inject Aiptasia-X right in to the buggers? shut everything off and shot em up.

 

If you do it in tank make sure to cover the entire area. When the aip's feel threatened they will release Planula. Where ever these macroscopic larvae land a new nem will grow.

The majano are easy kills just time consuming.

 

I got rid of them in a friends tank by removing the rocks to a bucket. and using a diabetic syringe to inject lemon juice into each one. Kept in bucket for a couple days and returned the rock pest free. They just fall off.

 

Darn it! I just made a call and its to late to delay my Coral order, they ain't shipped them yet, but they will be here tomorrow, 2 of the rocks I can pull out, I can then deal with the hydroids also, the rock with the majano is a different matter, will the rocks in a bucket with the lemon juice work on those majanos also?

 

If I remove the 3 rocks in question and do that, since most the rock won't be touched what kind of mini cycle would I get after returning the rocks to the tank? kind of concerned about that since my order will be here tomorrow.

 

Depending on rock size I would say no cycle.
You can also pull those rocks chip off the area with hammer and chisel or seal the buggers under super glue or epoxy.
