I’ll add my 2 cents, go with berghias. In full disclosure, I’m breeding and selling them. I’m out at the moment and this isn’t meant to be self promotion.
I’m growing aptasia all by itself in a tank and I can see how this nasty pest grows and consumes a reef tank. When you see a large aptasia in your tank what you actually have is a full range of them - babies, spores, the foot, and whatever you can see. The aptaisa in my tank reproduces in a few ways - dropping its foot like a mushroom, releasing spores which start as small balls and then lay a foot down and parts that fall off turning into aptaisa. This is probably how wands spread them around tanks.
In order to take down the full cycle of aptaisa, you need a solution that will attack the entire aptaisa cycle. That’s exactly what berghias do. If you have an egg sack, babies and mature adults, you will see results. The babies won’t eat medium or larger aptaisa until they get to a certain size but they will eat baby aptaisa. The juveniles and adults absolutely destroy them.
Hope that helps.
