Hikari ICH-X Water Treatment 4oz (73214) is a water additive for treating common aquarium parasites and related conditions, including ichthyophthiriasis (“ich”) and other protozoan problems. It’s used in freshwater and marine (including “marine ich”) situations as part of a quarantine or hospital-tank approach, helping you address visible parasite outbreaks by dosing directly into the aquarium water rather than treating individual animals.
Features:
- Treats ich (ichthyophthiriasis) in freshwater and cryptcaryonaisis (“marine ich”) in marine aquariums
- Targets multiple ich-related conditions, including velvet (gold dust), trichodiniasis, and saprolegniasis
- Uses a less harsh form of malachite green compared with traditional approaches
- Works as a separate treatment when used after PraziPro
- Formulated with formaldehyde (as listed), which is intended to be effective against the target organisms in-water
- Designed for quarantine/hospital tank use and consistent redosing based on the product schedule
Specifications:
- Product type: Water treatment / medication for freshwater & saltwater aquariums
- Key actives (as listed): Contains formaldehyde, methanol, and malachite green
- May stain: May stain silicone
- Dose (for ich / marine ich): 1 teaspoon (~5 mL) per 10 gallons of aquarium water
- Recommended tank setup: Use in a separate quarantine/treatment tank; do not stop filtration
- Filtration note: Remove activated carbon; clean or replace mechanical filtration media as needed
- Water change timing: Make at least a 1/3 water change before each addition
- Redosing interval: Repeat at least every 24 hours, but no more often than every 8 hours (follow product data sheet)
