Our tips for using Hornwort
The Hornwort is a must-have for community aquariums, trash can aquariums, and ponds. Use it floating for quick purification or planted for a more structured decorative effect. It naturally pairs with duckweed or Azolla to utilize light or with floating frogbit for an aesthetic complement.
"Hornwort is an irreplaceable plant for oxygenating and purifying a natural aquarium without filtration." — Mattier
FAQ Ceratophyllum demersum in aquarium or pond
Can Hornwort be planted?
Yes, but it also grows very well floating freely. Having no true roots, it only feeds in the water. Planting it is just an aesthetic choice.
Is it suitable for an aquarium without a filter?
Perfectly, it oxygenates the water very efficiently using only light as energy. The current created by the filter or pump then becomes unnecessary.
Does Ceratophyllum need a substrate?
No, this plant grows without substrate, directly in the water. Even bare soil suits it!
Can it be mixed with floating plants?
Yes, especially with duckweed or floating frogbit for a nice visual harmony.
Is it invasive?
It can become so if the light is strong enough and nutrients (nitrates and others) are abundant. In this case, simply remove the excess. You thus remove nitrates from your aquarium, trash aquarium, or pond in plant form!
