C-25 EVO OWNER’S MANUAL
C-25 EVO
Connecting separate lter equipment is a thing of the past with the C-25 EVO. A modern and
very eective RDF lter with little to no maintenance! This is a 3-in-1 lter that anyone can
install; mechanical lter (Drum Filter, RDF), bio lter (Moving bed) and disinfection (UV-C sys-
tem). This lter cleans itself when necessary, everything is fully automatic! It is not just a lter,
but years of experience combined with high quality materials!
This lter system removes dirt particles up to 70 microns in a quick mechanical way, removes
ammonia, nitrite and nitrate with a bio lter and kills bacteria, viruses and even fungi with
UV! The C-25 EVO is compact and reliable. It is a simple but very ecient lter system for (koi)
ponds, (large) aquariums and sh farms (aquaculture).
The housing of the C-25 EVO lter consists of a polypropylene (PP) container with an interme-
diate bulkhead. The partition is provided with a silicone sealing strip mounted on the ange,
separating the dirty water from the clean water. In the partition wall, there are 2 holes, which
are covered with a lid. In case of failure of the drum control, this lid may be removed so that
the water can ow past the drum, but without any lter function. Through this, the biological
ltration can still be operated until the error rectication of the drum.

Filter Overview
Drum Filter
The drum lter consists of a polypropylene (PP) box with two chambers. In the rst chamber
there is a drum with a lter panel. Water ows through the lter and the dirt sticks on the
inside of the drum. The special at nozzles spray the drum clean with water from the system.
The water with dirt is removed through the drain gutter into the sewer. The water level sen-
sor detects when the cleaning process should be activated. Due to this sensor, the lter only
rinses when necessary!
Bio Chamber
Once the grime and dirt particles have been removed from the pond water, the water then
enters the moving bed bio chamber where healthy bacteria is created with the help of the
white bio media. Harmful degradation is transformed into a healthy bacteria environment
that is then returned to the pond keeping the water clean, clear and stable.
Water Level Sensor
The water level sensor detects when the cleaning process should be activated. Due to this
sensor, the lter only rinses when necessary! At the beginning the lter will run a little more
often, but as the water gets cleaner you will notice that it will take longer. This also depends
on your ow and how many microns your lter panel is. We supply the drum lter C-25 EVO
with a 70 micron lter panel as standard, which we also recommend this for koi ponds.
