Crystal Bio Media 30-50mm 100 Litre Box
Crystal Bio is a special, environmentally friendly filter-media that is heated to temperatures above 900 C to produce a hyper-connecting glass cell structure. This results in media that have a surface area that is at least ten times larger than typical plastic substitutes. Furthermore, compared to other porous filter media, the weight is incredibly light: Crystal Bio weighs 7,5 kilogrammes for 50 litres!
Crystal Bio floats, take note!
ADVANTAGES: Crystal Bio medium has a porous cell structure with interconnecting spaces that allows for a large amount of biological surface area.
- Crystal Bio guards against pH lowering.
- Aids in reducing nitrates
