Mechanical and pre-filtration is the first stage of a healthy koi pond — it strips solid waste out of the water before it reaches your pump and biological filter. Shop rotary drum filters (RDFs), gravity and pump-fed sieves, pump pre-filters and strainers, and settlement & vortex chambers. Pulling solids out up front protects your pump, keeps your biofilter working efficiently, and delivers cleaner, clearer water with far less maintenance.
