A Koi pond uses smooth horizontal surfaces sloped toward a Bottom Drain to facilitate the easy removal of debris from the pond bottom. A water garden pond has gravel covering the horizontal surfaces with no Bottom Drain and must be manually cleaned to avoid unhealthful conditions for Koi. The Hybrid Pond™, like Koi ponds, uses a smooth bare liner horizontal surface sloped towards a Bottom Drain to continually remove debris from the pond bottom. The continual remove of debris from the pond bottom helps prevent possible unhealthy conditions.
Like the deeper depths of Koi ponds, the Hybrid Pond™ is constructed 3' - 5' deep or deeper. Deep water is healthier for Koi as it reduces stress, and the added water pressure increases the Koi's strength and internal organs. Deep water requires supplemental aeration to maintain dissolved oxygen levels at the bottom of the pond. So, like Koi ponds, the Hybrid Pond™ uses HydroAir™ aeration systems to blow millions of tiny air bubbles into the water to maintain high levels of dissolved oxygen in the water. Water garden ponds are relatively shallow at 24" or less, and thus, don't require the additional oxygen that Koi ponds and Hybrid Ponds™ do.
Hybrid Ponds™, like Koi ponds, are relatively deep. Deep water requires submerged circulation to maintain even distribution of dissolved oxygen and to "push" debris towards the Bottom Drain for removal from the pond.
In a Hybrid Pond™, submerged circulation is achieved by two methods:
- The HydroAir™ Aeration System's Air Stone is placed just above the Bottom Drain. As the air bubbles rise upward, the rising bubbles "pull" water upward with them. The water moves from the bottom of the pond to the surface. The rising water from the top of the Bottom Drain "pulls" water towards the rising column of air and water - this results in "pulling" water and debris towards the Bottom Drain.
- The water exiting the UV Clarifier is plumbed to the bottom of the pond opposite the Bottom Drain to "push" water and debris towards the bottom drain. This makes the Bottom Drain more efficient.
