Evolution Aqua Pure Aquarium Water Conditioning Filter Balls Algae & Greenwater Marine or freshwater usePURE Aquarium balls maintain crystal clear, healthy water in aquariums of all sizes. Inside every ball there are millions of live bacteria and enzymes which start to break down ammonia and nitrate once added to your aquarium. PURE Aquarium also breaks down organic waste which is often the cause of poor water clarity. PURE aquarium cannot be overdosed. To maintain crystal clear water add 1 or 2 PURE balls per 25 litres of aquarium water once per week.
