WATER VALUES FOR A HEALTHY FISH POND:

pH:  

7-8

GH:   8-12
KH:   7-8
NO2:   Max 0.15 mg/litre
NO3:   Max 50 mg/litre
NH3:   Max 0.15 mg/litre   

If your pond is new, tests must be carried out every 3 days for the first 6 weeks during the initial use of 

the device.

It is recommended to carry out an additional test after maintenance and after any change to the pond 
(cleaning, high temperatures, new fish, administering medication). It is beneficial for the pond to 

replace ± 10% of the water every week.

It is also important to remove dying hair algae from the pond to prevent them from extracting 
oxygen from the water and clogging up the filter and pump. We also recommend checking the pond 
water regularly for ammonia, nitrite and nitrate values during the initial use of the device. It is also 
recommended to limit feeding the fish during this period, as an excess of fish feed will stimulate the 

growth of hair algae.
Problems with the generation of oxygen could arise in a pond with a surplus of decaying substances. 

It is therefore advisable to replace 25% of the pond water after 14 days when using the Electrolyzer for 
the first time.
The Electrolyzer cannot be used at outside temperatures below 12˚C (October to March inclusive).

The Electrolyzer may not be used if you have snails or mussels in your pond that you would like to 
keep.
Even the smallest quantities of copper minerals are fatal for molluscs. The Electrolyzer can also not be 
used if you are breeding trout or salmon.

USE

Do not use in combination with clinoptilolite or other zeolites. Make sure you test the water before 

switching the Electrolyzer on. Ensure a minimum carbonate hardness (KH) of 7 ˚DH and a minimum 
total hardness (TH) of 8 ˚DH. The pH value of the water must be at least 7 pH (between 7 and 8). The 

ideal copper balance is between 0.1 and 0.2 ppm. The test strip will show you whether the copper 

content is too high or too low. If table salt or sea salt has been added to the pond water, the water must 
be completely replaced before you can use the Electrolyzer. If you want to use water conditioners, the 

Electrolyzer must be switched off for the period these products are used.

After the installation of the Copper Electrolyzer, it is possible that the fish in the pond could behave 

abnormally for a while, or show signs of anxiety. This is quite normal, and they will behave normally 

again after a while. If this behaviour continues for too long, however, you can switch off the Electrolyzer 

for a few days.

The Electrolyzer is switched on by pressing the “+” button on the display. The status of the copper 
emission will appear on the screen in red. This could be a figure between “0” and “99”. If the
