Hikari Ultimate Water Conditioner is a complete water treatment solution for freshwater, marine, or pond environments. It instantly "ages" tap water, eliminating harmful compounds and providing a stable, healthy environment for aquatic life. This all-in-one conditioner neutralizes ammonia, nitrite, chlorine, and chloramine, while detoxifying heavy metals like copper. It also adds essential electrolytes, boosts alkalinity, and replaces the fish's natural slime coat to reduce stress during water changes or new introductions.

Why Choose Hikari Ultimate?

  • All-in-One Formula - No need for multiple water treatments.
  • Fast Acting - Instantly detoxifies and stabilizes water.
  • Supports Fish Health - Reduces stress and helps maintain proper biological balance.
  • Safe for All Aquatic Life - Non-toxic and suitable for sensitive species.

PRO-TIP

Avoid using Nessler-based ammonia tests with Ultimate, as they will show false readings. Stick to salicylate-type kits for accurate results.

Not Recommended For

Do not use with permanganate- or chlorate-based treatments. Also avoid Winkler DO test kits as they will give inaccurate readings.
