Many nano and pico aquariums are already crammed even before the owner installs a filter. The new internal filter ProCristal i30 is there in the nick of time. With only 8 x 4 x 12 cm it fits into a coffee mug and still offers an astonishing cleaning performance for aquariums between 10 and 40 litres!
It is equipped with a separate filter chamber for special filter material against algae growth or for exceptionally clear water. There is a comprehensive range of special filter cartridges for the small filter on offer too. And for those who want to grow this baby into an adult, they can start by doubling the filter volume with the help of an extension module, and then go on extending it. It goes without saying that the JBL ProCristal i30 is safe for shrimps and juvenile fish.
