Bottom Drains
Utilizing Pond bottom drains is not such a mystery anymore… There are two main filtration options with your water garden koi fish pond. Pump fed and Gravity fed water garden koi fish pond filtration systems.
A gravity fed pond filtration system utilizing a bottom drain is preferred with a larger pond and needs to be built into your pond in the beginning. This method is preferred to reduce your overall pond maintenance. The idea of the bottom drain is that it uses gravity feed to draw water and mulm (the proper term for pond dust) to the filter system. Pond bottom drains do not pull solids off the bottom, they are designed to remove organics and particles from the pond and create a unique dynamic in the pond’s circulation system.
Ponds rely on beneficial bacteria colonies to breakdown fish waste, and other organics such as leaves, pine needles, pollen, dust and all other forms of water logged debris that typically settle to the bottom of a pond. Determining what size bottom drain is best for optimal flow rates and proper use of aeration, complements a pond drains ability to function properly.
Most ponds will require 3″ or 4″ bottom drain. 3 Inch bottom drains should optimally have a max flow rate of approximately 1800 gallons per hour and will service an 8′ diameter pond bottom nicely. 4 Inch Gravity Flow Bottom Drains should optimally have a max flow rate of approximately 3600 gallons per hour and will service a 10′ diameter pond bottom nicely.
