Bio Balls - Biological Filter Media - 2000 Pieces

Product Features
Product Reviews
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. Rock is an economical media used in pond filters because of rock's low cost and availability. It may seem like good material to use for a biological filter, but rock or crushed gravel is not the only material that can be used as a filter media and can be heavy to take out. BioBalls are fish-safe material that bacteria can attach to and is suitable for filter media in fish ponds. These are convenient for many as they float and when used in a media bag do a great job.

The important consideration is to keep the pollutants and unwanted debris out of our ponds, while keeping the beneficial bacteria in our systems.

A rule of thumb for fresh water ponds is to use about 1 ball for every 2 gallons of water for proper biological filtration.
