Marie I wouldn't worry too much as your corals look pretty healthy and uh if you can grow them faster than the pests can eat no worries, I think lots of people have it and don't even realize it.

anyhow if they are starting to do damage on your corals the first major sign is brown out on the pigmentation and at that point I would step in with interceptor.

If you do it when your corals are in a bad downhill position then you are more likely to lose a few pieces however if you do it when they are abit sick there is a great chance of recovery.
