Killing LR

[Scooterman]

The LFS would dry it out for a few days after then rinse again before using. I used a few smaller pieces just after drying out. You don't need much in a tub to do the job, like a cup or so. I never ran test or got into detailed testing of this, it is a last resort, lr IMO I wouldn't never just throw it away, If you can find others ways that works, then I'd try that first.

Have you seen any Isopods lately? I will have to search but it seems like 4 months is the magic number without fish for the starve out period. I had them in live rock I got from Fl last year and only found them after they had starved. It would be a shame to kill your rock after this time If the Isopods are playing out now. Without hosts their live cycle is supposed to be completely interrupted.

Some are falsely confusing harmless and healthy amphipods

with nasty predatory isopods
