is therefore particularly well suited for intensive long-term filtration in freshwater and ma-
rine 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, depend-
ing 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 pad
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.
(F4+F5) Filter foam pad
Set of one coarse foam pad and one fine foam pad for the middle section of the combi filter
basket. The coarse pad provides biological filtration through the colonisation of cleans-
ing bacteria. The fine pad traps particles of dirt which could damage the pump, as well as
providing biological filtration. The grooves on the top side of the fine pads are intended to
hold special JBL Stixx for long-term fertilisation of aquatic plants. The coarse pad should
be cleaned approximately every 6 months. The fine pad should be cleaned about every 4
months or as required (if pumping capacity deteriorates). Replace after cleaning three to
four times.

Cleaning the hoses
Bacteria settle in the hoses producing slime, which can significantly obstruct the flow of
water. Algae growth only occurs in strong light. The hoses should therefore be cleaned reg-
ularly with a cleaning brush (e.g. JBL Cleany). Simply rinsing with tap water is not enough!

Cleaning the impeller and casing
Turn the cover of the impeller casing anti-clockwise towards “Open” and remove the cover
by pulling gently.
Pull the impeller out of the casing. CAUTION: the impeller is held in the casing by magnetic
force. Take appropriate care when removing the impeller, making sure to avoid injuring your
fingers.
The ceramic shaft is held by two rubber bearings, which remain either on the shaft or on
the bottom of the impeller casing, or in the middle of the casing cover, when the impeller is
removed.
Clean the impeller casing, impeller and shaft with a suitable cleaning brush, then rinse in
clean water. Limescale can be easily removed by soaking in JBL Clean A (available at your
specialist retailer). Never dip the pump head in water or other liquid to clean it. Use a damp
cloth (e.g. JBL WishWash) to clean the surface of the casing.
