Description

The Aqua Rebell CO₂ Permanent Test Solution "CO₂ Check - 20 mg per litre" or "30 mg per litre" can be filled into any standard CO₂ permanent test and serves for the long-term monitoring of the CO₂ level in aquariums. An optimal CO₂-supply is essential for the thriving of aquatic plants and should therefore be continuously monitored. The advantage of the CO₂ Permanent Test Solution is that the determination of the CO₂-supply takes place independently of the aquarium water, thus substances such as humic acids cannot affect the CO₂ check.

Available in a 250 ml container.

A pipette for filling the permanent test is included in the delivery.

Application

The permanent test is filled with 1 - 2 ml of the CO₂ Permanent Test Solution and then positioned in a well-circulated area in the aquarium. After about 1 - 2 hours, the CO₂ content of the aquarium water can be read. A green colour indicates an optimal CO₂-supply of approximately 20 mg/l or 30 mg/l.

A CO₂ permanent test is very useful in an aquarium. Often, aquatic plants lack the essential CO₂, preventing optimal growth. With a CO₂ permanent test, the CO₂ level can be controlled with sufficient accuracy. The dye bromothymol blue used has the property of changing colour in a defined pH range.

CO₂ diffuses from the aquarium water through the air bubble in the permanent test into the test solution and vice versa. Depending on its CO₂ content, the pH value of the test liquid and thus its colour changes. A defined carbonate hardness in the test liquid determines at which CO₂ concentration a certain pH value is established. The test solutions "CO₂ Check 20 mg per litre" and "30 mg per litre" turn light green when their pH value is around 6,6. This is achieved at a CO₂ concentration of 20 mg/l or 30 mg/l. For this reason, the test solution "CO₂ Check 20 mg per litre" or "30 mg per litre" indicates a light green tone at a CO₂ value of the aquarium water of 20 mg/l or 30 mg/l. If the CO₂-supply in the aquarium is less than 20 or 30 mg per litre, the test reagent remains blue; if the CO₂-supply exceeds the mark of 20 or 30 mg per litre, the test reagent turns yellow.

Aqua Rebell

Aqua Rebell is our own aquatic plant fertiliser label. A great number of planted tank enthusiasts in general and aquascapers in particular use our products to supply their aquarium plants with nutrients.

When developing fertilisers and other aquascaping-related products, we work hand in hand with a base of aquarium enthusiasts and aquascapers, and we try to realise as many of their desires and ideas as possible. Quite often, ideas and wishes uttered in our aquatic plant lovers' and aquascapers' community www.flowgrow.de are the basis, on which we develop new products. These are then thoroughly tested by experienced aquarium keepers and aquascapers. Behind our product range, there are a lot of innovative ideas and long-term experience, and they are tested in real life. For us it is important that aquarium keepers and aquascapers are successful with our products and that they are thus enabled to make the utmost of their tanks and aquascapes.
