This 5 l pack of NEO MEDIA Pure XL is aimed at aquarists who run high-flow canister filters or sumps and want biological media that does not shift water chemistry. The manufacturer positions the Pure variant as neutral in pH, so it is meant for tanks where stable parameters matter more than hardness adjustment.
Why it matters
- Neutral pH effect: the manufacturer states that Pure does not raise pH in slightly acidic water or lower it in slightly alkaline water, and that it keeps pH around 6 to 7.
- Varied pore structure: pores of different sizes are meant to host several types of bacteria that break down waste, which the manufacturer links to the biological filtration performance.
- Claimed surface area: the manufacturer gives a specific surface of 3600 m²/l, with the figures reported from testing by Quantachrome Instruments.
- Size XL: the 5 l pack is designed for filters with strong flow or sumps, where a larger media volume is needed.
