Tip: Do not forget to clean all the hoses and pipes regularly with an appropriate brush
(e.g. JBL Cleany), as bacterial deposits on the inside of the pump drastically reduce
the pumping capacity of the filter.

Function and replacement intervals of the individual filter media
(F1) JBL Pre-filter media
Mechanical pre-filter media made of coarse foam cut into a T-profile to absorb as much coarse dirt
as possible. These media should be changed every 2 months. They can be rinsed once or twice.
(F2) High capacity biological filter balls (JBL MicroMec):
JBL MicroMec is a highly porous biological filter medium made from sintered glass and
with a special surface and pore structure, which provides excellent conditions for colonisa-
tion by beneficial cleansing bacteria. This allows an effective biological breakdown of pol-
lutants. It is therefore particularly well suited for intensive long-term filtration in freshwater
and marine aquariums. The round shape and varying diameter of the balls produce a self-
cleaning effect. As a result, 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 media to solve particular problems can be found in Chapters 12 and 13.
(F3) Filter foam (JBL UniBloc):
Foam pads with medium-sized pores for effective biological filtering thanks to optimal colo-
nisation conditions for cleansing bacteria. The pads have a section which can be removed to
insert filter media for special problem solutions. Careful cleaning is required every 6 months.
Replace pad after three to four cleans. Only clean or change one of the two pads at a time
and in alternation.
(F4) Filter foam
A fine-pored foam pad for the lower part of the new combi filter basket II.
The fine-pored pad catches particles of dirt which could otherwise damage the pump, and
is a biological filter. The fine pad needs to be cleaned about every 4 months or as required (if
pumping capacity deteriorates). Replace after three to four cleans.
(F1 + F4 = JBL Combi Bloc II)
(F5) Cotton fleece (JBL SymecPad)
These fleece pads are not a standard feature of the filter and are only available as an acces-
sory from your specialist retailer. High-quality fleece pads for mechanical fine filtering. The
pads can be inserted into any

filter basket. We strongly recommend their
use during the last filter step, e.g. as a replacement for the fine-pored filter foam pad in the
lower part of the combi filter basket II. The fineness of the SymecPads can result in a rapid
reduction of the filter performance. Therefore a change or a cleaning every 2 weeks is rec-
ommended.
