This set is for aquarists who run a JBL CristalProfi E filter and need to replace its filter media. It covers both mechanical pre-filtration and biological media, so a worn or depleted filter can be restored without buying the parts separately.
Why it matters
- Two sponge densities: the set includes one 20 ppi and one 30 ppi foam sponge, giving two different pore structures for trapping particles.
- Four pre-filter inserts: these catch coarse debris before it reaches the finer media, which reduces the load on the sponges.
- Tested plastics: according to the manufacturer, the foam materials were tested for harmful substances and do not release any into the water.
- Fast biological start-up: the manufacturer states that inoculating the media with JBL FilterStart shortens biological start-up to about 24 hours, compared with 1–2 weeks in freshwater without it.

What it works with
The set is designed for the JBL CristalProfi E filter and is intended for freshwater and marine aquariums that use this unit. Foam sponges should be rinsed in warm running water and reinoculated with bacteria, such as JBL FilterStart, before refitting. The manufacturer recommends replacing the sponges about every 6 months, because mechanical cleaning cannot remove all the dirt that builds up in the foam.

Frequently asked questions
The set includes 4 pre-filter inserts, 1 filter foam with 20 ppi and 1 filter foam with 30 ppi. The pack contains no other components.
In freshwater, colonization with cleaning bacteria takes about 1–2 weeks. Adding JBL FilterStart, a concentrated bacteria product, shortens the biological start-up time to about 24 hours.
Dirty foam can be rinsed under warm running water, but mechanical cleaning never removes all dirt. The manufacturer recommends replacing the filter foam about every 6 months.
According to JBL, all plastics it uses have passed testing for harmful substances and do not release any harmful substances into the water. Foam used with live animals is typically tested for this, since most plastics can release problematic plasticizers.
Yes, in seawater the initial colonization with cleaning bacteria takes twice as long as in freshwater. If the filter media has already been used, re-colonization takes twice as long again.
