Sera Siporax Ceramic Rings Filter Media 25mm

Sera Siporax ceramic media is a fully biological filter material for almost all filter systems.

Sera Siporax provides bacteria an extremely large amount of open-pored tunnel structures. This allows an ideal supply of  the bacteria with nutrients and a smallest amount of fresh water. There are oxygen-poor conditions within the tunnels. This makes the bacteria crack nitrate to get enough oxygen. Consequently, they continuously break down nitrate, and the water remains low in nitrate.

1 litre of Sera Siporax provides as much settling area for bacteria as, approximately 34 litres of clay filter material.

All sizes are packaged inside zip lock bags.
Available in the following sizes:

200g (1 litre)
600g (3 litres)
1kg (5 litres)
1.5kg (7.5 litres)
2kg (10 litres)
3kg (15 litres)
4kg (20 litres)
5kg (25 litres)

Calculation formula for pond use
One single liter sera siporax pond is sufficient for purification of 1,000 liters pond water with 20 pond fish of 10 cm length each or a comparable stock (representing approx. 1.5kg) of fish fed with up to 40g high quality food per day and release it from organic pollutions in long terms.
