i know squirting calcium in them kills them... i used it on some aptasia two weeks ago and its all gone.. :)

I have had excellent success killing aiptasia with a thin Calcium Hydroxide(kalkwasser)+water paste.  The syringe and plastic tip that comes with many Salifert test kits work great for getting the paste into the aiptasia.  I have yet to see an aiptasia survive this attack.  It only takes ~.2cc of paste to kill several of the aiptasia.  Much less costly than other methods.  Just don't blast your prize corals with the highly basic solution.

P.S. It has worked great for me...but...use at your own risk...

I have what you want! I'll give you some if you come by!

Sorry, I didn't see this post until just now.

The Kleins Butterfly loves those anemones and aiptasia. It doesn't bother much else for a while. It's not hard to remove the Kleins later with a trap. The club has the trap but you will have to visit MSM for the Kleins.

I found it at harmons.  You may just need to try a different one.  The one in kearns on 6200 South 4800 West had some last time I was in there.

Hopefully someone who has experience with calcium chloride will let us know if this is something that we can safely add.

Almost everyone who's kept a reef tank has added calcium chloride to their tank.  It's the "form" of calcium in almost every calcium additive on the market.  The only effect on the tank will be an undetectable increase in calcium .

Usually the product sold for pickling pickles is Calcium Hydroxide. I wonder if either one will work for that.

Calcium Hydroxide, also called Kalkwasser, Lime, and Pickling Lime is also used in the same way for killing aiptasia.

I understand that it can be found in large bags at Home Depot, though I get mine at the Chem Shop in Centerville because when I bought 12 lbs. it came in a nice plastic storage pail. But its cheaper at the grocery store.

Mark, what is it called at home depot and where do I look for it?

Jeff--- My address is in the above post!

Lime

The lime they use for cement? Cool!

There is no way to ensure the quality of cement lime.  It might be ok or it might not.  There are no heavy metal specs on a cement grade lime.  There are specs on a food grade product, which is why I use food grade.  I've never had any real problem finding pickling lime at the grocery store.  You'll never find it at Smiths, Albertsons or Walmart.  Try the smaller chains like Macys, Harmons or Dans.  And there is always the Mrs. Wages' online store.

Jon, is Turbo Calcium calcium cloride?

Yes. 

But Pickle Crisp is kinda expensive.

Great suggestion with the lights out methods. I hadn't thought about that. Wonder if it really works?

I had two majanos on a rock I bought from a club member a long time ago. I used hot water to get rid of them and it worked like a charm. I used it on two aiptasia as well. You do have to be really quick. You also need to use a hypodermic needle and penetrate and inject them as many times as possible. The reaction for me was immediate. Then I pulled them off of the rock and if there was any tissue left I scrubbed it off with a toothbrush.

That was almost 2 years ago and I haven't had any issues since. I also added a couple peppermint to try and keep it controlled.
