how do i detect when a certain number of Air Sac cauldrons are nullified?

[Narcosis]

In my map i've set it up so that the goal is surrounded by a large amount of crimsonator that make it impossible to reach so you have to nullify 6 Air Sac cauldrons to remove it.

I already know how to remove the crimsonator but i cant figure out how to detect when the Air Sac cauldrons are nullified. Can anyone help me out with this?
