How to Clean Matala®
Bio-filters are full of live micro-organisms. Filter
media are the bearers of this live. Over-zealous
cleansing or purifying the filter media will
unbalance the filter ecosystem by eliminating or
killing this essential live. Disinfecting or drying
of washed media only makes sense in cases where the
whole pond needs to be disinfected or dried out.
In essence, cleaning a bio-filter should be done
with the intention to:
Eliminate excessive organic waste (fish
excrements, excessive food, plant remains) from
the first section of the filter (sedimentation
chamber, vortex, etc...). Such need to be done
more often to avoid putting an extra burden on
the real bio-filter.
Rinse out excessive detritus or accumulated
bacterial flock from the latter section of the
filter to avoid plugging of the filter media,
which would create adverse anaerobic conditions.
Improve the living conditions of the nitrifying
bacteria and micro-organisms that thrive in the
Please note that when using Matala® media in a
well-designed bio-filter with proper flow rate it
will be difficult to see plugging of this media.
Excessive detritus or bacterial flock will tend to
slug of and settle to the filter bottom. Purging the
filter will take away this detritus.
To clean the real bio-filter section: "Use volume –
Create handles with strapping material in order to
remove R-Matala from chamber easily.
Matala® cleans very easily by the following methods:
Use water volume – no pressure: use a hose with
a sufficient diameter and pour a good volume of
water over the media.
Pour a full bucket of water over specific
sections of the filter media
Take out 2 sheets of Matala® and shake the
remaining sheets up and down in the filter tank;
drain the chamber.
Remove the media from the tank; dirty water
falls off; drain chamber.

Over zealous cleaning is not necessary and will
lose too much bacteria. Keep it gentle.
Shake the media up and down in the filter tank;
