Hikari ICH-X Water Treatment 16oz (73216) is a formaldehyde-based aquarium medication used to help treat common parasitic and related infections in both freshwater and marine aquariums. It’s commonly used in quarantine/hospital tanks to target “ich” (ichthyophthiriasis) and related disease conditions such as marine ich/cryptocaryoniasis and certain external protozoan and fungus-like issues. Because it’s designed as a separate treatment, it’s typically used when fish show symptoms and you need a controlled, medication-focused environment rather than treating the whole display tank.
Features:
- Helps treat ich (ichthyophthiriasis) in freshwater and marine ich (cryptocaryoniasis)
- Also used for velvet (gold dust), trichodiniasis, and сапrolegniasis as directed
- Uses a less harsh form of malachite green versus traditional approaches
- May stain silicone—use with care in aquariums and stands where silicone matters
- Often used after PraziPro as a separate treatment step
- Best practice is to treat in a separate quarantine/treatment tank and keep filtration running
Specifications:
- Product size (SKU 73216): 16 oz
- Treatment capacity: 16 oz treats up to 960 gallons (per product guidance)
