Many people here, (including myself) have used interceptor to treat for red bugs.
Dont worry... it's easy to handle.
Get water prepped up for a water change, (you want to have at least 20% made up).
Get a source of carbon prepped up.
You're only treating your display tank, so you dont need to treat your entire system, just anywhere you have them to include frag tanks.
Red bugs do swim, but they are acro specfic feeders, so wont be in your sump or fuge or anywhere else.
Stop the flow of all water to/from the tank to be treated, but leave any powerheads/closed loop pumps going for circulation.
Treat the system for 6 hours.
If you cant get the pistol shrimp out initially, dont worry, after 2-4 hours, the drug, (ivermectin) will begin to affect it and as long as you can get it out, it will recover fully. I had a similar issue with a blood shrimp during one of my bouts with red bugs. It was in the tank for over 4 hours and made a full recovery when I was finally able to remove it.
After 6 hours, begin to run carbon.
I like to run carbon for a full 24 hours following the treatment, then do the water change. However, I've also done a 20% water change and then run carbon....its up to you. I prefer carbon first since it will absorb any remaining ivermectin, (active ingredient in interceptor) before the water change is done.
You wont kill all your pods, the ones deep in the rockwork will survive fine and repopulate the tank.
Clams, anemones, soft corals, LPS, and SPS are not visibly affected during the treatment.....
Best bet is to carefully observe all incoming SPS afterwards...otherwise you'll end up reintroducing them to your tank....Ask me how I know....
