Care And Maintenance Of The Juwel Filter System - juwel TRIGON 190 Instruction Manual

Notice:
JUWEL EccoSkim combines the benefits of a surface skimmer with a compact design and great adjustable surface-skimming
capacities. With a performance of 300 l/h at a consumption of only 4.5 W, the JUWEL EccoSkim guarantees effective surface
skimming for freshwater and salt-water aquariums. Film and other surface-active substances are effectively removed and
conveyed to the JUWEL filter system and stored there. This can be ordered from your JUWEL Aquarium retailer (Part No.
87025).
Recommendation
OxyPlus - O2 Air Diffuser
The special OxyPlus - O2 Air Diffuser provides additional oxygen to the aquarium if
desired. This can be ordered from your JUWEL Aquarium retailer (Part No. 85145).

Care and maintenance of the JUWEL Filter System

The JUWEL Filter System requires very little maintenance if you follow the following
instructions.
bioPad
Replace the white filter wool pad once a week. If you have large fish, then this may
require changing slightly more frequently. This will ensure that the filter sponges will
not be clogged by larger dirt particles.
bioCarb
Replace the black activated carbon sponge every 4-6 weeks. Again, if you have
large fish then this may be to be more frequent. This ensures that any chemical
impurities from the water will be removed. Please note that the chemicals which are
absorbed by the activated carbon contained in the sponge, will be released to the
water again if the change intervals are too long.
bioPlus coarse/bioPlus fine
If the filter wool and the activated carbon sponge are replaced as suggested, then it
is sufficient to carefully clean or replace the coarse blue sponges at 6-12 weeks and
the fine blue sponges at 3-9 months only.
- Cleaning or replacing the blue sponges or the Cirax filter medium affects the impact
of the bacterial culture. For that reason, it is recommended not to clean or replace
the blue sponges and the Cirax filter medium at the same time, but rather
successively in an alternating manner.
You do not need to worry about the liquid dirt accumulating at the bottom of the filter
housing. Normally, this dirt contains important biological substances which enhance
the water quality.
Please do not worry if some dirt gets into the water during the cleaning process
causing cloudiness. After the filter system is back in operation, the water will soon
clear again.
Nitrax
In order to allow a proper level of micro-organisms in the filtration system it is
recommended to exchange the sponge every 8 weeks. The nitrate removal sponge
contains bacteria, which will after a while reduce the nitrate level in the aquarium
significantly.
