Hornwort is another world traveller that sets down roots in many types of water. We found gigantic colonies of this free-floating stem plant in a tributary of the rio Miranda at the edge of the Pantanal basin in South America. The stems grow at an astounding rate and require constant pruning. Ceratophyllum is known as a silver bullet against algae. And it’s easy to see why: the plant is greedy and quite simply removes the algae’s food source. We recommend using hornwort in every new setup.
