hardness (KH). Using the enclosed table, find the line or column with the carbonate hardness or pH value

Oxygen Test Set O
Special features:
The JBL Oxygen test set O
freshwater aquariums and in mains water and garden ponds within the range of 1 – 10 mg/l (ppm).
Why test?
Oxygen is the "elixir of life" for all animal organisms. All animals in the aquarium and pond need oxygen to breathe.
But also the "invisible helpers" in the aquarium and pond, the bacteria that break down pollutants, depend on
sufficient supplies of oxygen in order to be able to carry out their useful activities. Just as on our earth, the supply
of oxygen in the aquarium and pond is guaranteed by the assimilation activities of plant organisms (higher plants).
However, in aquariums and koi ponds without plants, or in marine aquarium the oxygen supply can only be
maintained by water movement and/or aerating e.g. by the use of diaphragm pumps (ProSilent range).
The following levels are recommended:
In freshwater aquariums and non-planted koi ponds, the oxygen concentration should correspond at least to
the equilibrium value (gas equilibrium with the ambient air) that can be achieved at the current temperature.
This level should be approx. 8 mg/l at 25 °C. The levels for other temperatures are shown in the following table.

The colder the water is, the higher the levels. Plants are capable of exceeding this equilibrium level by assimilation
activity. Accordingly, it is not uncommon to find towards the end of the lighting period (towards evening in garden
ponds) levels which are 1 to 2 mg/l over the equilibrium value in well planted aquariums and ponds.
