Hornwort is arguably the easiest aquarium plant in the hobby. It grows in virtually any light, any temperature (59-86°F), doesn't need substrate, and grows 1-5 inches per week. It's nearly impossible to kill.
Yes, Hornwort grows excellently as a floating plant. Many aquarists prefer it floating because it grows faster with direct light access and provides surface cover. You can also weight it down to plant it, but it has no true roots.
Yes, Hornwort is one of the best natural algae controllers. It grows so rapidly that it outcompetes algae for nutrients (nitrates, phosphates) and light. Many fishkeepers add Hornwort specifically to combat algae problems.
