Write a reviewFrank 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.
