This goes for fish, inverts, ANYTHING.
See the nodule behind the gill plate by the eye? That's what it starts out looking like.
So sorry to tell you this. I do not make it a habit to try to scare people.
I think a tank would need to stay dry for a couple weeks. If you're looking to nuke live rock, I'm currently in the process of baking my rocks in the oven. I hear it kills everything in an hour or less. Then gonna soak it in RO water to lets the die off fall away. But yeah, I'm just drying everything works the best.
I am no expert but I have a question for some of the pros on here. If he takes out all the fish and inverts and emptys the salt water. Can't you just fill the tank with RO water to kill off the parisites then empty the RO refill with new RO and add salt let the tank recycle then restock? I am just wondering if that would work.
I've done hyposalinity treatments in the past with good success for ich. Don't hear about it much these days, not sure why. Worked really well but needed to really track what you were doing. Not sure on any hardcore "gisms" surviving that. Aiptasia is damn near something from hell to kill off, being an electrical guy I like to "aiptaser" them. Tried a muratic acid dip once.... never again lol, those fumes suck. Never baked or boiled rock, would almost think freezing would be as effective when ya think about it.
Figure if anything of marine orgins lives through near fresh water conditions it's Gods will
