Oase Hel-X 13, an advanced biological filter media designed for koi pond filters & moving bed filters.
The Hel-X bio media has been redeveloped by Oase to further increase its biological settlement surface area by an additional 13%, giving it its name Hel-X 13.
Hel-X 13 consists of small individual bio mechanical plastic casings which allow beneficial aerobic bacteria to settle and breed inside its unique shape. This helps to biologically break down soluble waste to be filtered out while within the OASE ProfiClear Premium Moving Bed Filter Modules.
Because of its increased protected surface area, the bio media allows a greater amount of bacteria to be contained within the same sized filter volume. This gives a more rapid breakdown of food and fish waste in the system giving an all round more efficient filter creating healthier and cleaner water in the Koi pond.
The Hel-X 13 has a total surface area of 955m²/m³ (compared to 859m² of the older Hel-X) and has a protected surface area of 806m²/m³ (up from 704m²/m³ of the older media)
Just 25 Litres of the Hel-X 13 can reduce 170g of food and waste in a day.
While the Hel-X 13 has been designed to work with the OASE Pond Filters and Modules, it can be used in Vortex based & moving bed filters to increase their biological capacity.
