The reason I'm asking is that my dsb seems to need more infauna and I'd like to add some new live rock. I treated for red bugs with interceptor last year and don't want them again of course. Interceptor dips for new live rock would defeat my purpose too. I know anything is possible, but is it more likely they enter a system on untreated frags versus live rock that's probably been curing for the last month away from SPS?
