What is A Bead Filter?

Bead filters are a type of filtration system commonly used in koi ponds. They operate by passing water over a layer of small plastic beads that have a large surface area. These beads are usually coated with natural filter media, which aids in eliminating impurities and promoting the growth of beneficial bacteria. Bead filters are very effective at maintaining water quality in koi ponds and are relatively easy to maintain. Additionally, they can be used alongside other filtration methods, such as mechanical filters and UV sterilizers, to create a comprehensive filtration system for your koi pond.
