Marsilea Quadrifolia | Water Shamrock
Having Marsilea Quadrifolia, or Water Shamrock, in your pond is a very good thing because fish and bacteria use up oxygen continually through respiration, and need oxygen to survive. Many are also suitable and beneficial for cold-water setups.
Marsilea Quadrifolia, Water Shamrock, forms clover-like leaves that rise above the surface of the pond. Remove excess growth if necessary.
Only leaves that photosynthesize below the water surface can oxygenate the water. The best plants are those whose leaves grow underwater. They also remove nitrates, which helps to reduce algae and keep the water clear, meaning once established, many may be grown much deeper if sunlight can reach them.

The Water Shamrock grows well in my cold-water pond. It adds oxygen and helps keep the water clear. I noticed less algae after a few weeks. Easy to maintain and the leaves spread nicely.

Grew quickly in my pond with partial sunlight. The plant provides good oxygenation and helps reduce nitrates. I trim it occasionally to keep it from becoming too dense.
