Oase Pack Hel-x 13 Mm 20l - Egc
OAS-72731
High-Surface-Area Bio-Media for Large Filtration Systems
The Oase Hel-X 13 mm bio-media (20-litre pack) provides an exceptionally large surface area for beneficial nitrifying bacteria to colonise inside your EGC filtration system. More bacterial surface area means more ammonia and nitrite conversion, which translates directly into healthier water and healthier fish.
Superior Biological Performance
Each 13 mm Hel-X element is a precision-engineered plastic carrier with a complex geometry that maximises surface area per unit volume. The 20-litre pack fills a significant portion of your filter chamber with bio-capacity that traditional flat media cannot match. The lightweight, self-cleaning design stays in suspension within moving-bed filters, ensuring even colonisation.

How to Use
Pour the Hel-X media into the biological chamber of your EGC filter. The elements will tumble in the water flow, which keeps them clean and promotes even bacterial growth. Do not rinse new media in tap water — the chlorine can delay bacterial colonisation. Allow four to six weeks for the bio-film to fully establish.
Ideal for koi ponds with heavy fish loads where maximum biological filtration capacity is essential.
