Sera Koi Aqua-test Box

The water in the pond should be checked regularly so that preventive measures such as against algae can be taken quickly and easily, without the use of chemicals. Water is not simply water. Rainwater already absorbs pollutants and once it seeps into the groundwater, it is enriched with other substances that are not all suitable for garden ponds.

With the practical Sera Koi aqua-test box you can quickly and easily carry out the following tests:

• PH value
• Total hardness
• Carbonate hardness
• Ammonium / ammonia
• Nitrite
• Nitrate
• Phosphate
• Iron
• Copper

To ensure that everything runs smoothly in the garden pond, the water test case from Sera should not be missing from any pond owner. This is the only way to react quickly enough if water parameters are suddenly “out of control”.
