Jared, Good articles. although this has broght me back to the same question. the article on reefkeeping especially article 2 mentions several times that FW dips should be employed on new fish arrival.
"With all that I have discussed concerning freshwater dips my position on its use may seem a bit murky. Just to clarify, I do employ and advocate the use of freshwater dips when first receiving fish. I believe all fish that can be dipped should be administered this treatment prior to placement into a proper quarantine tank. This is done in an effort to minimize all possible parasitic infections. I do not, however, recommend freshwater dips as a cure for Cryptocaryon irritans. In my opinion, the repeated handling and osmotic shock of repeated dips are far too stressful to warrant its usage when other proven, but less aggressive treatments are available such as hyposalinity or daily water changes. Lastly, assuming freshwater dips can kill the embedded trophonts on a fish, once they are returned to the infected aquarium, they are just going to contract this pathogen again. So, I recommend using them and using them once only upon receiving the fish to minimize all possible parasitic infections."
any other opinons on this matter??
