Can No-ICH be used as a prophylactic?
No-ICH (as well as any other treatment) should not be added continually into any aquarium. You can however use No-ICH to help protect against ich outbreaks that commonly occur when new fish are added to an established aquarium. In this case we recommend adding an initial dose when the new fish are added and adding a second dose 2 days later. Observe your tank inhabitants carefully for any signs of outbreak to determine if you need to continue after the second dose.
