Hagen AquaClear 50 (formerly AquaClear 200) multi-stage filtration system provides optimal mechanical, chemical and biological filtration. CycleGuard now with BioMax preserves beneficial bacteria for a stress free environment. Invisible and harmless, beneficial bacteria are essential in the removal of toxic ammonia and nitrite. AquaClear's patented refiltration system allows you to control the flow rate without compromising filtration efficiency. When the flow rate is reduced, up to 50% of the water within the filter chamber is processed multiple times. More impurities are filtered out, creating a healthier tank with sparkling clean and clear water. Includes Foam, Carbon and BioMax Filter inserts. For aquariums 20 to 50 US gallons.
