The Tetra Pond test strips enable you to quickly and reliably determine the six most important water values in ponds in one simple step: dip the test strips into the water, swirl them in the water for one or two seconds, shake off any excess water and read off the most important information about the water values just 60 seconds later. The colour chart can be used to determine whether these are within the safe range. The pH, general and carbonate hardness (GH + KH), nitrite (NO2-), nitrate (NO3-) and chlorine (Cl2) in the garden pond water are measured.
Nitrite is the chemical that ammonia is converted into by filtration bacteria. It is less toxic than ammonia but is still potentially lethal to livestock. If levels are allowed to rise then fish will become diseased and die.
Nitrate is produced by the breakdown of toxic nitrite by the bacteria in your filter and will accumulate in your pond
pH is an important factor in keeping a pond healthy. Fish require a stable pH if they are to thrive.
GH and KH Water hardness is the measure of the total dissolved salt content in water
or the quantity of certain metallic ions. It is broken down into carbonate and permanent hardness. Carbonate hardness plays an important role in keeping the aquarium pH stable.
Chlorine may also be present in the water, and is harmful to fish and plants. Just like nitrite, chlorine should not be detectable in the pond water.
