Hornwort
Ceratophyllum demersum
Check HornwortHornwort is one of the hardiest and fastest-growing aquarium plants available, thriving in virtually any water conditions from cold to tropical. It can be planted in the substrate or left to float freely, where it provides excellent cover for fry and shrimp. Its dense, needle-like foliage absorbs excess nutrients rapidly, making it a powerful natural algae deterrent.

Seachem Flourish Liquid Fertilizer
While Hornwort thrives without supplementation, a small weekly dose of Flourish keeps its needle-like foliage a rich healthy green rather than the yellowed color seen in nutrient-depleted tanks. Its rapid growth means it quickly consumes available nutrients.
Tropica Premium Nutrition Liquid Fertilizer
Complete liquid fertilizer for vigorously growing plants like Hornwort. As one of the fastest-growing aquarium plants available, Hornwort is a heavy nutrient consumer — regular Tropica dosing helps maintain dense, healthy growth that shades out algae and oxygenates the water.
Seachem Prime Water Conditioner
Hornwort is one of the best plants for absorbing harmful ammonia and nitrites, but it needs chlorine-free water to do its job. Prime makes every water change safe and creates the clean water conditions where Hornwort can focus on nutrient absorption.
