I started my treatments for red bugs last night and thought I would post my steps, and how everything goes. To start I have a 57g tank with a PM30 sump, I'm guessing my system is between 60-70g. I'm using interceptor 51-100 lbs. tablets. Before starting, I removed as many shrimps/crabs/snails as I could. Interceptor can/will kill most inverts. For my size tank I desided to use half a tablet, I figured it would make it easy to dose the same amount for each treatment that way. I cut one tab in half then smached it into powder, then mixed it into a cup of tank water until dissolved. I then disconnected the air line from my skimmer, so it wouldn't skim..but still circulate water. Then poured the meds into the pump chamber of my sump so it would spread in the tank fast. That was at 10pm last night, 12h later....10am this morning I hooked the skimmers air line back on, then at 10pm tonight I plan to add a cup or two of carbon. Then I will run the carbon for 24h then remove and do a 10-15g water change. I will do these steps 3 times, spaced 5 days apart form start to start. After the last treatment I will do several 10g water changes spaced a few days apart. So far everything is going great, the few shrimp that got left in the tank did die (I thought they would), but all the fish and coral look great. Next time I mix up the interceptor I will take some pics to show what I did.
