Do NOT pour chlorine bleach into the top of the filter! This step is used when starting the filter
or during maintenance.
Establishing the bio layer
• The bio layer is the key pathogen removing component of the filter.
• A good bio layer will remove 90-99% of the pathogens.
• It may take up to
30 days to establish
the bio layer completely
• The water from the filter can be used during the first few weeks while the bio layer is being
established.
• The bio layer is
not usually visible
– it is not a green slimy coating on top of the sand.
Now the filter is ready for your daily usage. See the “Daily Usage” above for further
information.
