Overview
Why test? Carbon dioxide (CO2) is the most important plant nutrient. The consumption of CO2 differs from aquarium to aquarium and depends, amongst other things, on the following factors: number and demands of plants, carbonate hardness, water movement and light. Fertilisation with CO2 is usually done with a CO2 fertiliser system. In the aquarium water, a CO2 content between 15 and 30 mg/l is recommended. This range is safe for fish and at the same time ensures luxuriant plant growth. 20-25 mg/l CO2 has proven to be ideal. In special aquariums with a large number of plants, so-called scapes, higher values of up to 35 mg/l may be required. With this test you can determine the CO2 content of your aquarium water in mg/l and thus monitor the setting of your CO2 fertiliser system. The pH value, which can be read off at the same time, also makes it possible to maintain the pH value as constant as possible. This benefits the well-being of the fish and the health of the aquatic plants, without requiring any additional measurements. Please note: When fertilising with so-called liquid carbon, fertiliser monitoring with JBL ProAqua Test CO2/pH Permanent is not possible because these fertilisers do not contain CO2 but other carbon compounds. The indicator liquid therefore always remains blue.
