✅ Detailed Product Description

Ensure a clean and healthy aquatic environment with this premium activated carbon filter insert, specially designed for JBL CristalProfi i Series internal filters. Engineered to deliver superior filtration performance, this high-grade carbon insert effectively removes harmful impurities from your aquarium water, keeping it crystal clear and safe for fish.

The activated carbon absorbs and eliminates discoloration, unpleasant odors, and chemical residues—especially useful after using medication in the tank. Unlike regular filter media, this carbon is water-neutral and phosphate-free, ensuring it does not release any harmful substances back into the water, safeguarding the long-term health of your aquatic ecosystem.

Installation is quick and straightforward—simply replace the existing filter sponge with this cartridge, and your filter is ready to go. For best results, replace the carbon insert every 2–3 weeks or immediately after treating your aquarium with medications.

Suitable for fish tanks and freshwater aquarium enthusiasts who want reliable filtration and pristine water quality.
