EHEIM Substrat Pro Biological Filter Media 5L

EHEIM Substrat Pro Biological Filter Media 5L

Substrat pro offers perfect colonization conditions to the important purification bacteria through the high bulk density of the spherical shape and the perfect surface structure. Reduces peak nitrite loads, and can be rinsed and re-used several times.

Features:
=========
- Optimised bio-filter medium made from sintered glass
- High bulk density due to spherical shape (beads)
- Very dense colonisation of bacteria
- Longer intervals between cleaning
- Better reduction of nitrite loads
- Reusable (rinse carefully to clean)
- Suitable for fresh and marine water

Description
A highly active water purification with intensive biological decomposition of harmful substances

SUBSTRATpro consists of pearl-shaped sintered glass. The spherical shape gives a high bulk density. Thus the whole of the volume in the filter (filter baskets or modules) can be utilised. Also the optimum surface of the beads provides intensive colonisation of the important purification bacteria.

Due to the high number of bacteria, peak nitrite loads are more easily reduced and the maintenance intervals of the filter material are longer.

Tip:
Never clean or change all the filter media together in one operation (and never clean too rigorously). The bacteria cultures must not be completely destroyed, otherwise re-colonisation will be retarded.
