For aquatic plant aquariums and ponds

Carbon dioxide (CO2) is the essential element required by aquatic plants
for photosynthesis.  Most of the time sufficient carbon dioxide cannot
be generated naturally in the aquarium so is must be added as needed.
Therefore, consistent carbon dioxide monitoring is essential for
a healthy plant system.
Each kit includes a sample vial and reagents for 57 tests.

1. One drop of reagent (2) is equal to 2 mg/l of carbon dioxide.
2. The level of carbon dioxide is determined by timing the total drops by 2.
For instance, the level of CO2 is 10 mg/l if the total drops of reagent (2)
are 5 drops.
3. The level of carbon dioxide in the aquarium is influenced by the carbonate.
Hardness recommended level is a as follows:
5° dKH = 10~15 mg/l ; 10° dKH = 15~30 mg/1 ; 15° dKH = 30~40 mg/l
