Aquarium CO2 Drop Checker Solution 15ml

€5.99

Aquarium CO2 Drop Checker Solution 15ml.

It consists of a pre-made 4dKH solution containing the appropriate amount of indicator. Easy to use, no mixing required. Simply open cap and fill CO2 checker.

Fill the drop checker 2/3 full of CO2 Drop Checker Solution
Install drop checker inside aquarium
Optimum CO2 level is reached when indicator solution is deep green
Replace CO2 Drop Checker Solution minimum once a month to maintain accuracy

When the drop checker is submerged in the aquarium, the carbon dioxide will outgas from the aquarium water into the airspace of the drop checker and will eventually be absorbed into the indicator solution. The carbon dioxide gas will seek a point of equilibrium between the indicator solution and the aquarium water. As equilibrium is achieved, the color of the indicator solution inside of the drop checker will change based on the concentration of CO2 in the aquarium water.

If the indicator solution is green in color, then appropriate levels of carbon dioxide exist in the aquarium, and no action is required. If the solution in the drop checker changes to blue or yellow, then the CO2 levels in the aquarium are too low or too high, respectively.

Hi Fiona, Thank you for your question. Such small amount of drop checker won't affect the livestock :)

Ruben B. 08/09/2021

Your instructions read that the dropchecker should be mounted just below the watersurface. Some people argue that is not correct, as co2 is lighter than water and rises up. Meaning if you read good co2 levels at the top, you have bot enough co2 at the bottom, where the plants are. I personally would assume your solution already accounta for that. But as assumptions are killing, i would like to hear your thoughts on this. Kind regards, Ruben

Hello Ruben,
Thank you for reaching out to us.
You can place it at the opposite end of where your CO2 is injected, almost on the surface of the water or you can also go a bit down almost mid level. The checker fluid changes due to a PH difference when CO2 is added. The CO₂ checker is best placed at the opposite end of the diffuser. That way you are aware if CO₂ is reaching every corner or not. You can do tests to put it in different sides of your aquarium and see how it changes. Remember the gas diffusion rate in water is slower than in air so you can try moving the drop checker to many areas of your tank to get a good idea how well it's mixing.

Compré vuestro kit de dropchecker, y por error lo dejé caer dentro del acuario, el liquido es toxico? Si fuera toxico que puedo hacer?

Hello Ailish,

Drop checker solution is water with a value of 4dKH and some bromothymol blue.
You would need to have concentration values approaching 2000 ppm or higher to have any toxic effects, that being said a water change would not go a miss ;)
