 Chlorine harms fish - you DO NOT want it in your pond or aquarium!

Chlorine burns fish.  It can damage their scales/gills and, in some severe circumstances, it can kill.  Chlorine is added to drinking water in most parts of the world to kill bacteria.  It therefore follows that if you fill or top up your pond or aquarium you are adding chlorine to it and putting your fish at risk.

The equipment used to remove chlorine from water is called a dechlorinator.  In simple terms a dechlorinator works by passing water through activated carbon and out into the pond/aquarium providing checmically cleaner, chlorine free water.  The chlorine content in water varies from area to area and so there are no hard and fast rules as to how long the carbon will work before it is exhausted and needs to be changed.  However, the life of the carbon can be prolonged by regularly back-flushing the unit (this should also be carried out before use the first time).

Back-flushing the unit - you remove pre-filter and connect hose to outlet and then wash through.  Water then exits via the inlet. 

Water should be in contact with the carbon for approximately 4 minutes to enable it to absorb chlorine and any other impurities.  If you know how fast you wish to fill your system you can work out what size dechlorinator to buy.  Larger units contain more carbon and retain the water longer therefore enabling you to fill your pond/aquarium faster.  The larger the unit the faster the fill.

See sizes and flow rates of the dechlorinators below:
- small 12 litres capacity (180 litres per hour) 26" high x 8" diameter
- medium 20 litre capacity (300 litres per hour) 39" high x 8" diameter
- large 40 litre capacity (600 litres per hour) 46" high x 9.5" diameter

All units complete with pre-filter.  Full range of spares available.

Maintenance - change carbon annually and pre-filter when required.
