Product information

Clean and healthy water
Good water quality is necessary to ensure the health of fish and plants in aquariums. This can be achieved with various aquarium filters. Air is directed through the air hose into the CristalProfi i40 filter. After entering the air rises upwards, the water follows and flows through the foam pad to become mechanically and biologically cleaned. The fine air stone in the base of the filter creates very small air bubbles which flow a lot more quietly than bigger ones.

Easy to install
Rinse the foam pad under lukewarm water at the beginning and squeeze well. Activate foam pad with bacteria. Put air hose on air connection and place at arbitrary place in the aquarium. Connect hose with air pump. Install air pump at a dry and dust free place above the water level.

High biological degradation performance
The filter system is especially suited for aquariums with fry and shrimps. The animals find their food on the filter and there is no risk of them being sucked into the filter. The slow water flow promotes a high level of biological breakdown. The T-shaped filter material provides a large surface for cleansing bacteria and a long service life with good water flow.

Technical Data

JBL CristalProfi i40: The filter motor is simply too loud – isn't there a setting or another way to make it quieter ?

In principle, our JBL ProSilent S air pumps are designed as quiet pumps, but you will always have natural vibration due to the magnet in a diaphragm pump.

The airstone of JBL TekAir or of JBL CristalProfi i40 gets clogged after a few months.

The clogging of the airstone can happen with middle hard and hard chalky water. We recommend you put the airstone into JBL pH-Minus for a few hours. The airstone is also available as a spare part with the Art.No. 6141500.

What helps with green water in the aquarium?

Green water means floating algae, which grow when they have no competition from other plants and, even more, when the excrement of the fish creates excessive nutrient pollution in the water. The filter will not be able to do much about this. Ultimately, there are only two options:

1. Carry out significantly more water changes in order to remove the nutrients caused by fish excrement.

2. A JBL PROCRISTAL UV-C Compact plus kills off the floating algae.

A temporary measure is to switch off the light for 2-3 days in order to stop photosynthesis in the algae.
