Overview
The advanced Tetra BB Bio filter balls are especially designed to be used with the Tetra external filter EX series but can also be used with all other external filters and filter systems. The Bio filter balls provide a large surface area of 62 cm² each bal for the growth of beneficial bacteria and therefore for the effectively biological filtration of the aquarium water. Tetra BB Bio filter balls can be used several times.
Frank A. at 20.12.2018: Die Filterbälle haben zwar keine besonders große Fläche zur Besiedelung mit Bakterien, dafür ist aber die Durchflussleistung sehr groß und die Bälle sind praktisch unbegrenzt verwendbar. Ich nutze die Bälle als Abstandhalter zwischen zwei Schichten Filterwatte in den Filterkörben.
