What is safe for humans can be harmful or potentially fatal for sensitive fish, plants and other pond inhabitants. Therefore, your pond should only be topped up and replenished with pre-filtered tap water that is free of chlorine, chloramine and heavy metals.

Aqua Source Inline Dechlorinator
Aqua Source Inline Dechlorinator
The Aqua Source Inline Dechlorinator is a quick and simple method of filtering out harmful chlorine and other impurities from tap water. Ideal for first fills, water changes and top-ups. No need to wait for the chlorine to “gas off”, just fill up straight from the hose pipe. Made in the UK from the highest grade carbon for maximum efficiency. Tap water filtered by Aqua Source Inline Dechlorinator is free from chlorine and heavy metals, its purity means it won’t upset the balance of nature in your established ponds or tanks when used for topping up. The purified water is also conducive to the growth of healthy bacteria which means your bacteria filtration will mature in much shorter periods. Ideal for use where quality, efficiency and ecology issues are important. Read more

Aquaforte Phospat 1
Aquaforte Phospat 1
Phosphate is one of the main nutrients for algae (blanket weed) in a pond. With these filter cartridges it is possible to keep the phosphate level below 0,035 mg/l! This is the “magic” limit that is too low for algae to grow but does not harm plants and bacteria. When the cartridge is saturated it must be replaced (re-filling or regenerating is not possible). A great advantage compared to other phosphate binding products is that the Phospat does not release the phosphate at all! The phosphate binding capacities of the Phospat cartridges is 30-100 times more compared to Iron (III) oxides.
Features:
- Reduces phosphate in water and supports the biofilter
- Suitable for ponds, natural pools, fountains and circulation wells
- Adsorption capacity is approximately 90.000 mg (Phospat 1) or 270.000 mg (Phospat 3) phosphate
- Flow rate up to 1100 l/h (Phospat 1) or 3300 l/h (Phospat 3)
- Defined particle size of the individual layers
- Suitable for up to ±50m³ (Phospat 1) or 150m³ (Phospat 3)
- Several PHOSPATs can be combined for larger volumes of water
- The Phospat should be protected against contamination with appropriate pre-filtration – Max. working pressure: Phospat 1: 6 bar, Phospat 3: 4 bar

Kockney Koi Water Purifiers
Kockney Koi Water Purifiers
Kockney Koi Water purifiers are used to ensure your garden tap water is free of chlorine, heavy metals and other items that have been added, making the water totally safe for your fish. In simple terms the purifiers work by passing water through activated carbon and out into the pond providing chemically cleaner, chlorine free water. The chlorine and metals added to 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), and our Water Purifiers have a really easy to use back-flushing system added into it and gives a good amount of space inside the vessel to allow the carbon to percolate and move around when in back flush mode to give a efficient back flush system.
