With the made of glass GH-GOODS CO2 - Long-Term Test (Dropchecker) and the help of a test solution (optionally available) to be filled in and the displayed color of the test solution (according to the CO2 dissolved in the water), you can determine the optimal CO2 value for your aquarium on your CO2 device can regulate.

What is a long-term test and why is it so important?
With a CO2 permanent test you can determine the CO2 value in your aquarium and thus achieve an optimal value for your plants and fish. Permanent Test (or: Long-Term Test, Dropchecker) is made of different materials and in different shapes.
This variant of glass is attached by means of a suction cup in the aquarium. Filled with a reactive test solution, you will be informed via color changes whether the CO2 value in the aquarium water is OK, whether there is a supersaturation or even a CO2 deficiency.

We offer two corresponding test solutions (see accessories below)
- Test Solution calibrated for 20 mg CO2 per litre
- Test Solution calibrated for 30 mg CO2 per litre

The GH-GOODS CO2 - Permanent Test / Dropchecker is suitable for almost all aquariums.

Der Preis könnte abschreckend wirken aber der Dauertest hat keinen Grünstich, das Glas ist komplett durchsichtig!

Schöne, kleine Dauertests. Sieht auch in einem 10l Cube nicht überdimensioniert aus.
