Have you tried electrocuting them?

There was a thing a few years back in the hobby called a manjo wand or something like that. Basically it was a stick with a wire on the end that was electrified.

You would put the wire/stick in the nem and it was supposed to kill them.

Problem was a few weeks later reefers would see hundreds of new ones.

It was a great way to turn 5 nems into 100 nems inside 2 weeks IME.

What about carbon dosing? If you have biological filtration and a skimmer, you could carbon dose to cut costs and eleminate your need for water changes. You would just have to replace whatever elements the aiptasia needed for growth back into the water.
