Good luck. Do make sure you treat everything. When I had them a while back I pulled all inverts. Snails and stars will be fine. Shrimp, hermits and crabs should be pulled. As I said eariler dissolve the piece you use in tank water and pour in. Keep the skimmer running and let it overflow back into the tank if its an in sump type. Pull carbon as well but again let the reactor run with water only.
I dosed at night after lights out and 12 hrs later did a 20% WC and added carbon to pull out the medicine. I repeated this 2 more times 1 week apart. Though I did not see any living bugs after the first treatment. It's still unknown whether or not the are live bearers or egg layers, that's the reason for the 3 treatments. I have not seen a redbug since then.
For what it's worth, the first time I had them Was in my 20 gal I did only 2 treatments. When I upgraded to my 90 I once again found them. Not sure if they survived the nanos treatment or came in on something new. In the 90 I did three doses and haven't seen them since.
