under 4 KH (in fresh water) the carbonate hardness is to be increased. Therefore, we recommend
the aqua+KH tablets by Aqua Medic.
4. Maintenance and Care
The quantity of CO dissolved in the water depends mainly on the carbonate hardness. The higher it
2
is, the more CO gas is dissolved – at the same pH-value. The harmfulness limit of the CO
2 2
concentration also depends on the carbonate hardness.
A so-called free carbonic acid (dissolved CO gas) belonging to it is necessary in order that the
2
calcium and magnesium ions (those which build carbonate hardness in connection with CO gas)
2
keep being dissolved. The free carbonic acid belonging to it (also called equivalent carbonic acid) is
important for the plants. The equivalence between carbonate hardness builder and CO is stipulated
2
from pH 7.1 – 7.4 for fresh water (8.1 – 8.4 for salt water). This quantity of CO is not dangerous
2
for fish, it does not depend on the carbonate hardness. The plants consume the equivalent carbonic
acid at the assimilation (photosynthesis). If it is not permanently supplemented, the carbonate
hardness builder can break down (so-called biogenetic decalcification). This should be avoided in
any case.
The Aqua Medic CO -complet compensates for this loss.
2
It is very important to replace only the CO and not to supply the aquarium with more CO . For a
2 2
balanced ambience it is important to get the calcium carbonic acid equivalence. The plants only
receive enough CO (carbonic acid) when this equivalence is maintained.
