These BioBalls are made for use as a biological pond filter, with a textured surface that allows for beneficial bacteria to colonise on them. Every box includes 250 BioBalls plus a media bag with a drawstring, while each ball offers a surface area of 30 square inches.
The BioBalls Biological Filter Media is designed to optimise bacteria growth in biological filtrations units. They use a paddle wheel design to break waterflow, which helps to de-gas the water and maximise the dissolved oxygen levels. The BioBalls don’t break down like some traditional biological media options, giving you years of simple use without the need for replacement. Their compact size means they can be placed into smaller spaces, and their centre channel allows them to be strung together for quick and simple cleaning.
