PURE Aquarium is a combination of the correct strains of bacteria and enzymes delivered in biodegradable balls containing a food source which will achieve the following benefits in a freshwater aquarium:
• Crystal clear and healthy water
• Reduces organic waste
• Maintains a biological equilibrium
• Reduces BOD / DOC / TSS
• Reduces ammonia and nitrite
• Reduces filter and tank maintenance
• Reduces maturation and start-up times following a filter crash
Regular use of PURE Aquarium will ensure that your fish live in a safe, healthy and crystal clear environment. 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 filter, ideally held in a filter bag.
• 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 FAQs
What is PURE Aquarium?
PURE Aquarium is a live bacteria and enzymes in a unique gel ball delivery method.
How does PURE Aquarium work?
Bacteria are suspended in the ball until placed into aquarium water. When fish go in, ammonia is produced, and the bacteria leave the ball to feed on the fish waste. The ball shrinks and the bacteria coat the substrate, decoration and filter media. Other bacteria are also contained in Pure which clear...
Where do I place PURE Aquarium balls?
Ideally, place Pure Aquarium inside the filter, in an area that will contain it. You may need to use a filter bag to keep it in one place. Areas of water flow are best, and if you have to, you can drop Pure Aquarium straight into an aquarium containing small fish. Large fish over 15cm may try to eat...
Can I overdose PURE Aquarium?
No, but it does contain aerobic (oxygen demanding,) bacteria, so strong surface agitation and/or aeration from an airpump and airstone is encouraged.
Is there any PURE Aquarium left over when I use it?
Yes, Pure Aquarium balls shrink down over time leaving a small 5mm bead. This can be left in the filter with other filter media, or removed and discarded.
I can’t see Pure Aquarium Bomb in the packaging. Are you sure there is something in there?
Yes, an interesting optical illusion happens when Pure Aquarium is placed in water – it turns invisible! Pour the contents into a fish catching net and you’ll see the ball, then tip into the tank..
What’s the difference between Pure Aquarium and Pure Aquarium Bomb?
Pure Aquarium Bomb is best for set-up of a new aquarium and filter, and Pure Aquarium is best for regular addition and long term maintenance. Adding Pure aquarium into long established aquariums should see the water getting clearer and appearing more polished, within 24 hours..
Can my fish eat it PURE Aquarium?
Yes it is possible for a large fish to eat Pure. It is only gel and friendly bacteria, but it should be discouraged. For any fish that is large enough to ingest Pure Aquarium, either in its hydrated or shrunken form, place it into the filter and contain it.
I’ve added Pure Aquarium to my system and nothing has happened?
As soon as Pure Aquarium is placed into an aquarium with fish, and dechlorinated water of the correct temperature, something will happen. Bacteria will leave the ball in their millions and seed the aquarium. You can’t see them but they are there and working, and Pure’s bacteria has been independently...
