This semi-formal pond or water feature has a two-stage biofilter built in to keep the water clean. Water is pumped up through gravel where bacteria turn ammonia into nitrates which are then taken up by the plants as food.

Removing the excess nutrients like this is key to keeping water clear, especially when there are fish in the pond. Algae will otherwise grow rapidly, turning the water green.
