i give my fish a salt water dip to cure ick on the fish it work fast . put fish in salt water foe about 3 to 5 seconds then put back in tank
I am curious as to how this works, do you have any more info? I know it is an effective method with many unprotected parasates, but I can't see it working with ich.
Aside from the tank and gravel issue pointed out by Blinky, Ich is highly protected and cannot normally be killed when on the fish. none of the ich meds can hurt it while it is still on your fish, and only a very few meds can kill it while it is in the substrate. As a general rule it is only vulnerable when it is in the free swimming stage. Does the salt water make it fall off the fish? Thus removing it from the tank?
There would still be an issue with needing to treat the tank, but 3-5 seconds in salt water if effective would seem less stressful than other methods. one could then put the fish in a seperate tank and treat the main tank if it worked.
