Hose installation leaks and draws in air Check all connections are airtight and fit correctly.
Airstone too close to suction pipe
If air is additionally provided by a membrane
pump, check that there is sufficient distance
between the airstone and the suction pipe.
“IN” and “OUT” hoses mixed up Reconnect hoses correctly
High flow resistance due to dirty filter material or
filter material in net bag
Clean filter material and do not fill long-term filter
material (JBL MicroMec, JBL SintoMec) in finely
meshed net bags. For special problem solutions,
only use the original CristalProfi filter material
with the appropriate foam edge.
Stopcock on pump head stiff
Cause Solution
Washers do not glide
Dismantle hose connection block (7) and spray
the stopcocks with commercially available silicone
oil. Reassemble hose connection block and move
stopcock backwards and forwards a few times.
Fish dead and/or water cloudy
Cause Solution
Nitrite poisoning due to too rapid change from
“old” to “new”. Cleansing bacteria thrown away
with old filter.
Run an old and new filter parallel for 2 weeks in
the same aquarium or incorporate 1/3 of the old
filter material in the new filter. Never carry out a
“general clean up” of the aquarium at the same
time!

Filter material with foam edge
The following filter material kits are constructed according to a new two-stage principle which
is specially designed for the CristalProfi Filter “e” range. They are comprised of a core section
and an edge section. The core is made up of a relatively fine special filter media requiring a
finely meshed net bag. The edge consists of coarse foam. With this design, the water flows
slowly through the special filter media providing optimum efficiency, whilst at the same time
the overall water flow through the filter is obstructed as little as possible thanks to the coarse
foam edge. The size and volume of each kit is measured specifically for the filter basket of the
JBL CristalProfi e range.
