Pond Maintenance

Koi and goldfish ponds normally contain livestock from a variety of different environments. These environments must be free from common tap water contaminants such as chlorine and heavy metals as some fish are extremely sensitive to them. To eliminate these contaminants a dechlorination system is typically used. If there are also high levels of chloramine, nitrates, fluoride and bacteria present in the water, our Aquatics Heavy Organics Removal Page offers the relevant advice for the removal of these.

It is becoming more common for reverse osmosis to be used by koi keepers following the dechlorination stage to provide purer water directly to the pond. Using water that has been through a RO system can help maximise the coloration of the fish due to the quality of the pure water. Sometimes it is also necessary to remineralise the water after filtration to achieve the desired Carbonate Hardness (KH) and General Hardness (GH) levels.

Treatment Process

1

Particle Removal

Our cartridges offer outstanding absorption of sediment, dirt, sand and scale flakes to prevent filtration systems from blockage and microorganism growth.

2

Chlorine and Organics Removal

Carbon cartridges are a long established choice for the reduction and removal of chlorine, VOCs and heavy metals whilst reducing water hardness.

3

Reverse Osmosis

Pure water (permeate)  is produced during reverse osmosis by applying pressure to force water through a semi permeable membrane, leaving a majority of the present ions and dissolved solids on the other side to drain as waste (concentrate).
