At Kayhays Gardens we have been designing and installing water features for over 25 years, complete with pumps and filtration. We import an excellent range of bio-balls, perfect for use in your biological filtration system.

An important part of the filtration process is the inclusion of bio balls. The advantage of bio balls is in their ability to be very effective substrates for nitrifying bacteria They are also unrivalled in their ability to oxygenate the water.

A biological pond filter is a filter that uses biological means to remove harmful ammonia and excess nutrients from the water. The bio filter should be run 24 hours a day, creating what is known as the nitrogen cycle.
