Filter insert with phosphate remover for JBL CristalProfi i range.
Key Features:
• Solves algae problems by removing the algae nutrient phosphate from the aquarium water.
• Just insert the filter cartridge into the filter basket of the JBL internal filter (CristalProfi i 60, 80, 100, 200) instead of the filter sponge.
• Completely ready for use with inner pipe. Can be refilled with JBL PhosEx ultra if required.
• Replace after 2-3 months or check phosphate content with JBL phosphate test and use new filter insert if phosphate level has risen again (or refill with JBL PhosEx ultra).
