I use Tropic Marin Pro Coral Cure for dips. This is a iodine solution. This will not take care of all pest. Often many pest can still make it through dips. AEFW has been reported of making it through dips. Also you will need interceptor
[hr]
for dipping for red bugs. It is really best to qt if possible.
Please do not be fooled by thinking if buying from a reputable store you will be fine. Any store that move many corals through their tanks stand a good chance of picking up some pests.
