This is something new and starting to gain momentum in the LFS to gain your trust and business. If you ask them to dip your corals prior to them bagging them they will do it, sometimes for free depending on how much you buy sometimes for a small fee which is worth every penny. It's safer and more delicate on the corals than doing it at home which we will do anyway but at least you can see plus know it's clean in front of them that no pests are coming out. I used to bring my own dips in the past and do it at their stores prior to bagging them. This way when they get home it's acclimation and in to quarantine.
