Kalkwasser - Also known as Calcium Hydroxide, kalkwasser is capable of killing Aiptasia. However, I don’t recommend this extermination tactic. In order to work, you must precisely fill the Aiptasia with a concentrated dose. If you try killing too many in this way, you can inadvertently raise your tank pH level, which is no good.
has one tired this method? I have a bottle of Kalkwasser and I have a 35 gallon tote that I could put the rock in and let it soak for a few ours to let the Aiptasia die off.
