Hagen AquaClear 30 (formerly AquaClear 150) 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.
