I just bought a large colony (10" x 6" sheet) of Mohawk Zoas. My LFS (who is a long established, well known coral coral breeder and business owner) said that I could simply dip in fresh water RODI for 10 minutes to remove pests. Also said that even if there are any Ick eggs that they would "burst" being in fresh water for that long. Was told no real need to quarantine , that the fresh water RODI dip would be 99% effective. Thoughts?
