Koi & Pond Tip of the Day

Ponds with vinyl liners or of fiber glass construction tend to show a decrease in alkalinity over time and may need supplements to maintain an acceptable level. Raise alkalinity by adding Calcium Carbonate, concrete blocks, oyster shells, limestone, or even egg shells.

Koi Pond Filter Media

We carry a wide variety of replacement filter media for your Koi pond.

Bacteria convert harmful by-products from aquatic animals into less harmful nitrates. This process occurs naturally in nature's lakes and streams. In a Koi pond these bacteria are found on the walls of our ponds. They also can be found on the inside walls of the pond plumbing, attached to the skimmer basket, and on the rocks that form a waterfall.

The reason it is important to consider what filter media to use when we build biological filter systems, is to increase the available surface area for these bacteria to colonize. The important consideration is to keep the pollutants and unwanted debris out of our ponds, while keeping the beneficial bacteria in our systems.

If you have any questions regarding the proper media, feel free to contact us for help.
