The Correct Amount Of Co And The Correct Ph Value; Setting The Amount Of Co - JBL PRO FLORA u502 Handbuch

whilst at the same time providing plants with their main source of nutrients. Thus luxuriant plant
growth and lively, healthy fish are guaranteed.
How much CO is needed to maintain a particular pH value depends on the KH in the aquarium.

The higher the KH, the more CO
content can be calculated. The following table saves you making the calculations and also
shows the pH values which you can set as an optimum value without any risk to your fish.

recommend having this option activated.
12.2 The correct amount of CO
JBL recommends a CO
marked with "CO correct " in the table above. 20 – 25 mg/l have proved to be ideal. This level is
