Maintains crystal clear and healthy water

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

Pure aquarium

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 Bomb

Fast acting live filter bacteria

Joining the award winning PURE Aquarium range is PURE Aquarium Bomb, the unique,
clear, live bacteria gel ball for use in aquariums.


PURE Aquarium Bomb is a much larger single treatment dose of live nitrifying bacteria
designed specifically at cycling new aquariums and making them ready for fish. It also
rapidly combats water quality emergencies in new and established freshwater aquariums,
when life threatening levels of ammonia and nitrite are detected.


Beneficial bacteria inside the filter can be lost through cleaning media under the tap,
replacing mature media with new, or the use of medications. Increased fish numbers,
uneaten food and dead, decaying fish can also lead to levels of ammonia and nitrite.

Pure Aquarium bomb

Please note: PURE AQUARIUM BOMB is not intended to clear green water.

An appropriate UVC is recommended to clear green water. Simply place PURE Aquarium Bomb directly into the main aquarium or better still into a space within a biological filter. One Bomb should be used per 200 litre aquarium, and will even work with a full stocking of fish.

Its live bacteria and enzymes in a unique gel ball delivery method.

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 water, and help reduce organic waste.

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 it, which should be discouraged.

No, but it does contain aerobic (oxygen demanding,) bacteria, so strong surface agitation and/or aeration from an airpump and airstone is encouraged.

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.

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..

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..

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.

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 tested and counted. The least visible difference will be on a mature, healthy, well filtered aquarium with already crystal clear water, but even then solid waste levels may be lessened in the tank and inside the filter. The most difference and benefit will be seen in dirty, poorly filtered tanks, with water clarity and quality issues.
