Hyposalinity to treat ich, how low and what species?

[Luis]

I just wanna let you know that by now the hospital tank is arround 1.014 ( I think tonight is going to be arround 1.010) the spots are gone! .... but I notice something else: in the display tank the remaining fish have one or two spots (three more clowns, a sargeant damselfish and a blue tang) but I've noticed that the lawnmower is scratching a lot, I guess he has more spots but is difficult to see in his skin, I'm not gonna be able to catch it because that means to take all the rocks out and I don't wanna stress the whole system... the question is: do you thing all the fish in the system can get ich inmunity, I've heard it takes two months, do you know if that's a rule or they can get worse? like I told you before the ich got into my system a month ago and the fish that still in the display are eating as usual. What do you think?

Thanks.

I think a healthy fish that is not stressed by tankmates, environment or poor food can easily fight off Ick without any intervention.

It is highly probable that when you return the fish in quarantine to the ich invested display aquarium, they will promptly become infected and you'll be right back where you started.

I tend to agree with Guy. I just introduced three green chromis to my 30 gallon. Of course, all my fish except the clown came down with ich. Well 4 of the 5 then. Clean water, a diligent skunk shrimp, and no activity near the tank. One week later. No ich. My orange spot goby had a minor bout with it when i added the clown a month and a half ago. I rarely treated my freshwater fish for it either (18 yrs).
