Just something to keep in mind.
Couple of years ago a guy from Red Sea was out here and @Moolis had hosted an evening talk at Pet Stop.
One of the questions asked was why do Aiptasia X not remove these pests as claimed, they always come back in bigger numbers.
The reply was that adult aiptasia could spawn as you attack them, resulting in babies popping up shortly after the attack. You must redo the attack on those babies before they are matured and respawn when you eventually take care of them. The window mentioned was 43 days. Must do the second round before 43 days, when they are matured enough to respawn.
This 43 days would apply to all methods. So do not be like me and be lazy...
