Clean and healthy water:

  • Plant and food remains and metabolic substances lead to a deterioration of the quality of the water in the aquarium.
  • Good water quality is necessary for healthy fish and plants.
  • This can be achieved by aquarium filters.
  • The filters suck in the aquarium water and remove the pollution and waste materials from the water.


  • The JBL ProCristal has its own filter chamber for dedicated filter material to combat algae growth or for especially clear water.
  • The aquarium water flows slowly over a large surface area into the filter, where it is cleaned and then pumped back into the aquarium.


  • Thanks to the fine pores there is no risk of small fish and shrimps getting sucked in.
  • EXTENDABLE - The filter can at least be doubled thanks to one or several extension modules. JBL grants a guarantee of 4 years.



Can I adjust the performance of my JBL ProCristal i30?

> The first generation of the small internal filter for 10-40 l aquariums had only one swivelling water outlet. The new generation has a swivelling and adjustable water outlet so you can regulate the flow. With the spare part 6099800 "JBL ProCristal i30 water outlet with adjustment" you can easily convert your existing device.


My filter has become loud after a few months. What’s the reason for that?

> The impeller of the filter is subject to constant wear and tear. We recommend you replace it. This way its smooth running is ensured. Make sure that the noises are not caused by trapped air.

The guarantee covers defects in material and assembly. The guarantee does not cover parts subject to wear and tear, such as the impellers or shafts as well as damage caused by external influences and improper handling.
