My aiptasia story..........
My 125 was literally overgrown with them a couple of years back. I used the lime juice, Aiptasia X, boiling water and so on. I even bought the fish that was told would eat them. No luck
Then I read how people was shooting them with Kalk. Well, I wasnt going to buy that just to kill the pests, so I found out that pickling lime is basically the same thing as Kalk and I bought a bag.
I kept the syringes from the many bottles of Aiptasia X and used that for the lime. To date, no aiptasia in my 125g....the 155g has some tiny ones in it, but bought peppermints for that and they are doing their job. Back glass was covered with little ones that I couldnt reach and after putting the peppers in, they were gone within 2 days.
I mix the lime just enough so it goes into the syringe (the one that comes with Aiptaisa X) All I do is cover the mouth and when it shrinks up into itself, I cover the whole thing and it melts those pests away (also works on majonos (sp) Some of the lime gets on other stuff, but isnt enough to hurt it. I just wave my hand to get it off if I feel it will burn whatever it falls on.
I also use the lime to control the GSP that grows on a big piece of live rock. I make a boundary with it or if the GSP has already grown onto a spot I dont want it on, I squeeze some onto the GSP and it kills it where I put it. Doesnt hurt the rest of it.
The lime hasnt ever affected the water in any way or the other corals and I have softies, LPS, and SPS in all my tanks. I dont ever remove the lime once it has killed whatever it is Im wanting to kill. It dries hard and eventually will flake off and fall to the sand where it becomes part of the sand bed. No spikes in PH, no harm whatsoever that I have seen.
Ive always zapped as many as my arm allowed me to, not worrying about what it will do to the water because Ive tested after zapping literally hundreds within 2 days time and it didnt affect the water.
Now the only time I need it is when I get a new coral that some may come in on or I need to control my GSP. I dont even turn off my power heads when I apply it. The aiptasia readily take it as if it were food, giving one time to fill the disk of it full. For safe measures, I shoot it and cover the whole thing once it retracts, and I never see another one even near where that one was killed.
I found it rather therapeutic when I was going after the ones in my 125g, was my " thinking" time....Before I knew it, I had zapped the whole tank and there was no more to zap. I liked the challenge of finding them as much as I did the zapping them........=)~
