Hornwort does much more than sway peacefully in the water and add pretty foliage to your pond or aquarium; it oxygenates the water and keeps algae growth to a minimum. Not only does its bright green leaves look beautiful in the aqua blue of your fish tank, but it also helps make your aquarium a better and cleaner environment for your fish. On eBay, you can find a great selection of this living plant, which will benefit both you and your aquarium or water garden, as this oxygenating plant reduces the amount of maintenance and upkeep that can take unnecessary time out of your daily schedule. And the best part of incorporating this plant into your aquarium is that it is so self-sustaining that you barely need to care for it at all. Just minimise its light exposure to less than eight hours a day and hornwort will grow, thrive, and keep your aquarium or pond clean and healthy. Don't let your aquarium or pond grow murky and foggy because of excessive algae growth, as planting hornwort is quick and easy.
