Filter material to use with foam edge
The following filter materials are most effective in a relatively slow water flow. In the e-series
JBL CRISTALPROFI
F3 (JBL UniBloc) is pre-cut so that an oval core area can be taken out and replaced by special
filter media in finely meshed net bags. Optimal efficiency is thus achieved by the water flowing
slowly through the special filter media, whilst at the same time the medium-sized pore struc-
ture of the foam edge means that the overall water flow through the filter is obstructed as little
as possible. The following filter materials are suitable for this purpose:
JBL CarboMec - High-capacity active carbon
Removes residue medication, water discolouration and high molecular pollution from fresh
water and salt water. Virtually no increase in conductivity and phosphate levels in the water.
JBL PhosEx ultra - Solves algae problems by reliably removing phosphate
Prevents and eliminates undesirable algae growth by removing the main nutrient, phos-
phate, from fresh water and salt water.
JBL NitratEx - Nitrate remover
Eliminates nitrate from fresh water. Prevents and eliminates the growth of undesirable algae
by reliably removing the nutrient, nitrate, from fresh water. Exchange resin can be regener-
ated with cooking salt.
JBL ClearMec - Pollutant remover for crystal-clear water without algae trouble
A mixture of clay pellets and special resins removes the pollutants, phosphate, nitrate and
nitrite, from fresh water, thereby preventing undesirable algae growth. The clay pellets pro-

filters, a slow water flow is achieved by a two-stage principle. The filter foam
Solution
Dismantle the hose connection block (7) and
spray the stopcock ball valves with commercially
available silicone oil. Reassemble the hose
connection block and move the stopcock lever
back and forth a few times.
Solution
Run the old filter and new filter parallel in the
same aquarium for 2 weeks or incorporate 1/3 of
the old filter media in the new filter. Never carry
out an "over-all clean up" of the aquarium all at
once!
