How it works

The HappiFilter is designed to work in harmony with your aquarium’s natural biology, keeping your fish happy and your tank balanced.

  1. Water Circulation
    Your aquarium water flows through the HappiFilter, where it’s evenly distributed to create the perfect environment for beneficial bacteria.

  2. Biological Filtration
    Inside the filter, our specially designed filtration chambers provide a home for billions of beneficial microbes. These microbes break down fish waste and naturally clean the water without harsh chemicals.

  3. Plant Support
    On top of the filter, you’ll find the nitrate removal chamber, where you can grow decorative houseplants. Their roots thrive in the nutrient-rich environment, helping absorb and recycle extra compounds from the water while adding beauty to your aquarium. Let the plants clean the water for you.

  4. Cleaner, Happier Aquarium
    The result is healthier water for your fish, less maintenance for you, and a thriving mini-ecosystem right in your home.
