I used to use a Kalk Wasser mixture. However it was impossible to contain the chemical, it floated through the tank.
The Aiptasia -X mixture work well.

This product is good if you only have a few aphasia in your tank. If you have an outbreak, I recommend peppermint shrimp or the "wand". I had mixed results with the product but overall the problem got worse. A gang of 10 peppermint shrimp have contained it and seem to be getting the infestation under control. If I could go back this would be a last resort.

best product for aiptasia ive used other than prevention.

Works good So far.... Time will tell!

the stuff really works,but best yet was when i forgot to add it to my initial order.i emailled brs that i forgot and they sent the item by mail instead, toll free. due to the fact that my order had already been shipped earlier that morning.. you can`t ask for a better service then that !!! thats a plus plus to all.. thanks again, how could any one ask for more.. bill

Amazing results, this product is no joke works rite away as soon its applied never seen anything like it....

I bought this because I had picked up a couple Aiptasia come in on a coral frag. I have never had these before so I was not sure what to expect. I only have a few that pop up every few weeks. As they pop up I use this product and they are gone. Just wish I could catch them before they reproduce. One squirt of his product and they die within minutes.

As advertised

Well, after trying peppermint shrimp, file fish, copper banded butterfly, all of which would munch down the "tiny" aiptasia, but not the 2" long "mothership", I turned to this effective but expensive solution.

It took one treatment - one - and I wasn't even sure I was doing it right. I read the instructions, read around in forums for tips, turned off all powerheads pumps and sump return pump, gave the system a good 45 minutes to let ALL water movement settle down.

I used the curved tip on the syringe - I drew up maybe 2cc's of this stuff after shaking it through an entire half hour TV show (I hear a lot about the importance of shaking it to combat separation, and I figured not like I could "overshake" it.

I them put my hand slowly into the water, syringe first. I got down within 4-5" of the little ***** "mother" aiptasia, squeezed a little out to let the "mother" smell it, waited about 10 seconds, halved the distance to 2" away, squeezed another tiny amount out, wow, I'm this close to this thing with a syringe and it hasn't retracted!?! So far so good.

I then ever so gently moved toward the center of "mother disc" while squeezing tiny amounts out - tiny tiny amounts - then when I got to the outer "tentacles", I went for it - I shot the rest of the syringe full bore into the center of it. A second or two later, it retracted. Darn it, I thought, it caught me in the act and now I have a blob of Aip-X on top of a p***ed off aneonome that would probably spread like wildfire now that it was so rudely disturbed.

I watch and wait, and as I gave up and turned off the 10k's for the day going down to the actinics, I saw the little "implosion" they show in the videos, I thought. Hmmm. Maybe, but I'll see what I see tomorrow.

Tomorrow came, I turned all the lights on, and "mother" was nowhere to be seen - just a little white good (aip-X) where it used to swing about. About a week later, still no sign of the "mother" and the natural predators killed off all of the "baby" nuisances. Another week went by, and still nothing - WOW was I relieved - as I was ready to toss out the beautiful piece of live rock this thing was attached to, which would have required a full re-rockscaping since it was on the bottom.

Bottom line: Expensive, but if you take your time, effective. If you have big ones that thenatural predators won't touch, this is the answer - just keep some predators around for the "babies" - I can't see myself having the patience to try and hit every one of the tiny ones, failing, screaming...

I love this stuff. It doesn't hurt my corals at all of the aiptasias are too close

I got this because I had a small aiptasia problem. I tried a couple of peppermint shrimp, they didn't touch it and I had one red legged hermit crab that would eat it sometimes, but it just came back. I used this and the aiotasia just shrank up and disappeared. I accidently got some on a coral and I thought I had killed it, but it didn't seem to affect it at all.

Works great! Move slow and follow the directions and you'll love the results!
