JBL Internal Filters Aquarium

JBL internal filters provide mechanical and biological filtration inside the aquarium. This category includes complete CristalProfi m greenline, CristalProfi i greenline and ProCristal i30 filters as well as extension modules, filter cartridges, outlet accessories and replacement parts.

Select a complete filter according to aquarium volume, required flow, available installation space and the needs of the livestock. For an existing filter, identify the exact model and series before ordering media or spare parts. Components for CristalProfi m, CristalProfi i and ProCristal i30 are not automatically interchangeable.

Check whether filter sponges, cartridges, outlet parts or other accessories are included with the selected product. Additional modules can change the available media volume, while spray bars, wide outlets and Venturi components affect water return and aeration. Product pages provide compatible models, dimensions, output and supplied components.
