when my fish get ich. i just have to leave them in the tank. i do a lil bit more water changes and use a lot of selcon and garlic guard on all my foods when i feed. it always seem to take it away after 3-5 days
lcstorc is right in that the Ich has not just gone away, nor is she wrong in saying that not losing fish to Ick does not constitute having a tank free of Ich. No experts dispute that opinion.
Neither Garlic or Selcon (amino acids) will not cure a fish or a fish tank of Ich, nor do cleaner gobis or cleaner shrimp pick off the Ick. They will lessen the intensity of Ick infestations, but will not fully stop them.
There are many reports in print that are written by researchers and the information has not changed over he years, nor have new treatment methods been discovered. Lee's posting on Ich mentions at least one of those researchers several times.
Immunity can be built up to an Ich breakout on individual fish, but that immunity can also be lost by an individual fish. The levels of break out in healthy "immune" fish are just so light that they are usually just not noticed or are considered something other than Ich. Eye bumps are quite often Ich and seldom does anyone holler Ich and quarantine all their fish.
Most people just put up with low level, nearly unnocticeable break outs of Ick that they assume just went away or think are somthing else. Then when a new fish comes in the reef keeper old fish that are not immune to the new Ich therefore a break out that is undisputable starts and they again think they had no Ich before but think they now have it again.
The only information put out by Lee or lcstorc that I have a problem with is the statement that the salt water Ich cycle is not effected by temperature, because that is still disputed between different studies by different researchers.
