bacteria. The ring shape allows the flow of water to be channelled through in any direc-
tion, guaranteeing optimum circulation through the filter. Cleaning is required every 6 – 12
months, depending on the amount of dirt. Replace when the dirt can no longer be washed
out.
(F3) Filter sponge (JBL UniBloc):
Medium-pored foam pads for effective biological filtering with ideal conditions for coloni-
sation by cleansing bacteria. The pads have a section which can be removed and replaced
with filter material to treat specific problems. (section D). Careful cleaning is required ap-
proximately every 6 months. Replace after cleaning 2 to 3 times. Only one of the two pads
should be cleaned or replaced at a time.
(F3) High capacity bio filter balls (JBL MicroMec):
JBL MicroMec is a highly porous bio filter material made from sintered glass with a special
surface and pore structure, which provides excellent conditions for colonisation by ben-
eficial bacteria. This allows an effective biological break down of pollutants. It is therefore
particularly suitable for long-term filtration in freshwater and marine aquariums. The round
shape and varying diameter of the balls produces a self-cleaning effect, with the result that
this filter material only needs rinsing briefly every 6 – 12 months, depending on the amount
of dirt. Change when the balls begin to disintegrate. Filter materials to solve particular prob-
lems can be found in Chapters 12 and 13.
(F4+F5) Filter sponge
Set of one coarse and one fine foam pad for the middle section of the combi-filter basket.
The coarse pad provides biological filtration through the colonisation of cleansing bacteria.
The fine pad traps particles of dirt which could damage the pump, as well as filtering biolog-
ically. The coarse pad should be cleaned approximately every 6 months. The fine pad should
be cleaned about every 4 months or as required when indicated by a reduction in pump
capacity. Replace after cleaning 2 to 3 times.

Cleaning the hoses
Bacteria settle in the hoses producing slime, which can significantly obstruct the flow of wa-
ter. Algae growth only occurs in strong light. Clean the hoses regularly with a cleaning brush
(e.g. JBL Cleany). Simply rinsing the hoses in tap water is not sufficient!

Cleaning the impeller and casing
Turn the cover of the impeller casing anti-clockwise in the direction "Open" and remove the
cover by pulling gently.
Take the impeller out of the casing. CAUTION: the impeller is held in the casing by magnetic force.
Take appropriate care when removing the impeller, particularly to avoid any injury to fingers.
