DIY Project 1 - Pond Biofilter

• Tremendous job by Mr.Pete in building his own biofilter for his own use.
• He research and build a biological filteration system for the existing pond.
• The most common biofilter uses various sizes of gravel as the filter media in an out-of-pond box.
• Many include a prefilter to trap large particles before they reach the biofilter media, extending the time between cleanings of the biofilter.
• A bottom drain is a common feature for flushing sediment and muck out of the filter.
• Most filters also provide some means for aerating the water to create an oxygen-rich environment for the bacteria that colonize the media.
