Velvet

[Jaws]

Ya from what I've read, hyposalinity won't kill velvet but hyposalinity still involves a low salt level. Pure freshwater wouldn't include any salt which you would think would kill everything. I just hope it kills everything in all stages. It's too late about killing the live rock too. I've had the tank full of fresh RO water for a couple days now. The rock was cleaned with Bleach and Muriatic Acid before it was put in the tank so there wasn't much life on it anyways but at least it was cycled. I just don't want to put the fish back in there after 6-8 weeks only to find that velvet could survive in freshwater and have to start all over. Again.
