Description

The manufacturer of NEO MEDIA has made every effort to create one of the best biological filter media on the market – this is determined not only by exceptional, varied porosity – but also by long-term durability – and by the media’s impact on water pH – an aspect often overlooked Some ceramic media can affect water pH – did you know that? Water pH tests indicate that many popular ceramic and ceramic-like media have an alkaline effect – meaning they can raise pH and significantly increase water hardness – examples include: Siporax pH 9-10 – Substrate Pro pH 8-9 NEO MEDIA PURE is a truly neutral filtration material with minimal impact on pH – it does not raise the pH in a slightly acidic aquarium – and it does not lower the pH in a slightly alkaline aquarium Suitable for all aquarium types – planted – shrimp tanks – Malawi – Tanganyika – marine aquariums including SPS corals NEO MEDIA Pure does not change pH – helping keep it stable in the 6-7 range NEO MEDIA is available in three variants – PURE – SOFT – HARD – which respectively – do not change pH – soften water – harden water Varied porosity The production process and fibre structure make it possible to create media with pores of different sizes – allowing fast colonisation and growth of different bacteria responsible for breaking down harmful waste – the ecosystem that develops inside the media is a key factor in biological filtration – this type of varied porosity is not available in fired ceramic media – where pores are typically the same size Largest surface area Advanced production technology combined with fibre structure delivers record porosity – far exceeding the best-known ceramic media to date – Siporax 270 m²/L – Substrate Pro 450 m²/L – Matrix 700 m²/L – NEO MEDIA offers up to 3600 m²/L – this surface area, combined with varied pore sizes, supports top-level biological filtration – the final stage of production ensures long-lasting durability – completing the key advantages of this biological filter media Quality confirmed by Quantachrome NEO MEDIA was tested by Quantachrome Corporation laboratories using Quantachrome Instruments – all product data is provided based on an assessment issued by an independent group of Quantachrome researchers Bacteria included Inside the carton, in a separate package, you will find nitrifying bacteria to speed up the start-up of the media – they look like small black pellets – pour them between the media inside the filter
