Water Hyacinth

Water Hyacinth is a fast growing aquatic plant with stunning lavender-purple blooms. Beyond its beauty, it’s a powerful natural water purifier that pulls out nutrients and contaminants faster than nearly any other aquatic plant.

Why It’s great for goldfish systems

Ultra-Efficient Natural Filter:
Water Hyacinth rapidly absorbs nitrates and ammonium, stripping out the excess nutrients that cause green water and algae blooms. In warm, sunny conditions it can double in size every 1–2 weeks, making it one of the fastest natural water-cleaning plants available.

Heavy Metal & Contaminant Absorption:
Its thick, fibrous roots act like living filters, trapping and absorbing heavy metals such as lead, copper, zinc, and nickel, as well as other impurities from the water. This makes it ideal for ponds or tubs where you want crystal clear, balanced water quality.

Perfect for Goldfish Breeding:
The soft, dangling roots make excellent natural spawning material for goldfish and koi. Eggs easily cling to the root filaments, providing both protection and aeration for developing fry.

Thrives Indoors or Outdoors:
Water Hyacinth grows beautifully in outdoor ponds, tubs, or even indoor aquariums when given bright overhead lighting and nutrient-rich water. Provide at least 10 hours of strong light for steady, lush growth year-round.

Fast-Growing & Effortless:
This plant thrives on neglect, no soil needed, no CO₂, and no complicated maintenance. Simply float it on the surface, remove extra plants as they multiply, and enjoy cleaner, healthier water.

Important — invasive & legal note:

Salvinia Minima is an invasive aquatic plant outside its native range and can rapidly form dense mats that choke waterways and harm native wildlife. It is illegal to release Salvinia minima into natural waters, and several U.S. states regulate or prohibit its possession, sale, or release. Check your state’s aquatic plant rules before buying or transporting this plant.
