Re: Highest ammonia uptake by which plant? From my experience with non-filtered tanks, floating plants that develop larger leaves and roots do the best job.
They have free access to CO2 from the atmosphere, so they can process alot more nitrogen as food than any submerged plant. Small duckweed doesn't seem to scale up like the giant duckweed, salvinia or especially water lettuce.
My vote is for water lettuce (Pistia stratiodes).
Hydro that has pushed thought the water surface should also do a really good job, but it typically doesn't grow that way, at least right away. |
