Hikari Ich-X Aquarium Treatment is a proven solution for treating ich and other protozoan-related diseases in both freshwater and marine fish. Based on the well-known Leteux-Meyer formulation, it uses an improved form of malachite green to deliver effective results while being less stressful on fish and biological filtration.

This ready-to-use treatment helps control common external parasites and fungal issues and can be safely used on scaleless fish. It remains effective even in cooler water conditions down to 50°F, making it a reliable option across a wide range of setups.

Why Choose Hikari Ich-X Aquarium Treatment?

  • Proven Formula: Based on the Leteux-Meyer formulation with an improved malachite green component.
  • Effective Parasite Control: Targets ich (ichthyophthiriasis) and marine ich (cryptocaryoniasis).
  • Fungal Support: Helps control common external fungal issues.
  • Fish Safe Design: Can be used safely on scaleless fish when directions are followed.
  • Low Stress Treatment: Designed to be less stressful on fish and bio-action.
  • Cool Water Use: Effective in temperatures as low as 50°F.
Treating ich? Before you dose, check our step-by-step guide + calculators to avoid mistakes and stop it from coming back.

Dosing Instructions

  • Use 1 teaspoon (5 mL) per 10 gallons (38 L) of aquarium water.
  • Perform at least a 1/3 water change before each dose using a sulfate-free conditioner.
  • Repeat treatment every 24 hours, or as often as every 8 hours depending on severity.
  • Continue treatment for at least 3 days after all visible signs of disease have disappeared.

Best Practices

  • Always treat fish in a separate quarantine or treatment tank when possible.
  • Remove activated carbon from filters during treatment.
  • Maintain filtration but clean mechanical media if needed.
  • Add aeration during treatment to support oxygen levels.

Legitimate Product

I wanted to leave a review as this website came up during a Google search for Hikari Ich-X Aquarium Treatment, but I questioned the legitimacy. Product came as highly recommended by aquarium hobbyists online. This was the only store within Canada that I was able to find this product, at least online. Quick shipping within Ontario and the product we received was legitimate. Bottle arrived with the lid slightly bent but useable. No content has spilled out and the bottle was intact. We did not end up using it as the mild case of ich that we had started to notice cleared up with a temperature change, however, we are happy to have it on hand ready to go as we introduce more fish and plants.

Only buying it here from now on

Bought Ich-X from another seller on Amazon before and it didn't help at all. Sadly, I lost all my fish. Not sure if it was counterfeit or just a bad batch. When I saw it was available in Canada again, I checked with this seller and they confirmed they're an authorized dealer. This time it worked great. Definitely sticking with this store.

No more deaths 😄

No more deaths after I started using this product ! Has 9 fish die very quickly before I could get my hands on this stuff. Literally a life saver. Started dosing as per instructions, large water changes, raised the water temp. Big change after that.. little white spots disappearring. Fish are spot free but still need to continue for a few days to break the cycle.

Hard to Find, Works Great

I’ve been using Ich-X for years and it’s always been one of the most reliable treatments I’ve tried. It works really well for ich, fungal issues, and other external parasites, and I’ve never had problems with fish reacting badly to it.

With all the restrictions, it’s been almost impossible to find in Canada. I honestly haven’t seen it available online for about 4 years. During that time I had to try other products, but they just didn’t give the same results.

good price and works very well

as most of us know it’s always a bit of trial and error figuring out what actually works when fish get sick last time i used ich-x it worked great i’ve got a 30 gallon tank with guppies and shrimp and recently something started taking out a couple of fish i tried a herbal treatment first but it didn’t really help after seeing the fish flashing and rubbing against things i figured it was likely ich or something similar used ich-x at half dose because of the shrimp and it cleared it up ended up losing one fish but the rest recovered and the issue was gone
