I've dipped pretty much every type of coral in Bayer as well with no problems, however, I use 0.5ml to 2 cups tank water. This dosage has removed every pest for me (including pests from LPS, SPS, and softies).
I would definitely dip LPS. I've seen a huge surge in the number of LPS pests lately, such as LPS-eating spiders, various LPS-eating pods, etc.
