OASE Hel-X 13 Filter Media - 1 Litre

OASE patented Hel-X 13 filter media is designed to have a substantial surface area to house beneficial bacteria to assist in the filtration process and breakdown of toxic waste products in the aquarium.

Ideally placed at the bottom of the filter where debris and sludge collects, the bacteria housed in the media will breakdown toxic waste and convert it into safe gases which are essential in the health of aquatic plants and fish.

Supplied in a 1 Litre quantity, this will fill one tray inside the BioMaster External Filter.
