PURE Aquarium is a bacterial treatment for aquariums of all sizes. Inside every ball there are millions of live bacteria and enzymes. Once added to your aquarium, the bacteria and enzymes inside each ball will start to break down the ammonia and nitrite in your aquarium’s water. PURE Aquarium also breaks down organic waste, which is often the cause of poor water clarity. PURE Aquarium will leave your water crystal clear and healthy.

Regular use of PURE Aquarium will ensure that your fish live in a safe, healthy and crystal clear environment. With over 20,000 million live bacteria per litre of Pure Aquarium, your aquarium will shine, especially if you replenish them monthly. The Pure bacteria balls are made from a biodegradable polymer, and crammed full of bacteria that are slowly released when they are needed most smoothing out the peaks and troughs in your ammonia/nitrite cycle.

We recommend that you use PURE Aquarium as part of your regular maintenance programme. You cannot overdose with PURE Aquarium.

To maintain crystal clear, healthy water add 1 or 2 PURE Aquarium balls per 25 litres of water once a week. Add the balls directly into your aquarium or inside the aquarium filter.
If using PURE Aquarium for the first time or if your aquarium has clarity problems, add 5 to 10 balls per 100 litres of water. When water clears, continue to use as described above.

PURE Aquarium can also be used when starting up a new tank, to help to mature your filter.
