Example: the hardness of the mains water is 20° d, the osmosis water 1° d. The
required mixed water should have a hardness of be 5° d. The cross-calculation then
should look as follows:
The following calculation was made: 20 – 5 = 15 and 1 – 5 = 4 (negatives are ignored).
Accordingly, 4 parts of mains water (20° d) and 15 parts osmosis water (1° d) are
needed to obtain mixed water of 5° d.
For regular partial changes of water (approx. 20 % every 2 weeks), the mixing
proportions should be calculated on the basis of the amount of water to be changed.
Any water which has evaporated may be supplemented with pure osmosis water.
2. Using pure osmosis water
If the mains water contains pollutants (mostly nitrate, phosphate, copper etc.),
pure osmosis water is used. The hardness required by the particular fish kept (see
specialist literature) can be set by adding JBL Aquadur plus without the risk of
introducing pollutants, which would be unavoidable if mains water were used for
mixing. Pure osmosis water is also used to fill marine aquariums, adding the required
amount of salt.
Technical data
Maximum capacity: 136 l (36USG) in 24 hours at a water temperature of 24°C and a
minimum 3 bar pressure.
Capacity under practical conditions: approx. 60-100 l in 24 hours at water
temperatures of between 10 and 15°C and a pressure of 3-6 bar. Higher temperatures
