Go to a drug store and buy the syringes that they use to feed medicine to babies. Or just ask at the (pharmacy) counter, they might just give you one.
I tried kalk paste before ordering more Aiptasia-X. The good thing about A-X is that it sticks to the aiptasia. The kalk paste went a bit wild on me and I had to dust it off other things before it could kill things I didn't want killed.
But I guess there are different aiptasia just like any other coral so something might work for one aiptasia strain and not for another.
Peps DID eat some of my aipts, but then they died....I can't keep peps alive in my tank for some reason.
