Begin pulling an dipping your SPS on a weekly basis, they are quiet voracious. You need to dip now, otherwise your corals will become too weak and perish.
You don't have many acropora, consider placing all of those species in a separate system for dipping.
If you're thinking their is a easier way out of this, think again. It's like having an apartment complex infested with bed bugs. You don't know which tenant brought them in, they're in the walls, everywhere. The only way to rid them are to remove and quarantine the tenants or nuke the entire building.
In the case of our aquariums, you can't simple nuke it and expect the SPS to survive.
