Evolution Aqua PURE Aquarium – 50 Ball Tub
Crystal clear, healthy water made easy. PURE Aquarium is a natural bacterial treatment for freshwater aquariums of all sizes. Every ball contains millions of live bacteria and enzymes that break down ammonia, nitrite and organic waste, the most common cause of cloudy water, leaving your tank clear, healthy and safe for your fish.
Use it as part of your regular maintenance routine, or when setting up a new tank to help mature your filter.
