Reasons Why Your CO2 Drop Checker May Not Be Changing Colour

There are a number of legitimate reasons why your CO2 drop checker may not be changing colour. You may be using the wrong indicator solution, or you may simply need to change the fluid more often. Either way, you should be able to find out the cause of the problem and take action to resolve the issue.

CO2 drop checker doesn't monitor CO2, it monitors pH

A CO2 drop checker is a simple liquid test kit that provides continuous monitoring of the carbon dioxide (CO2) level in your aquarium. The device works by transferring CO2 from the air in the tank to the reagent liquid, which changes colour over the course of an hour. A green colour means high levels of CO2, while a blue one indicates low levels. Some of these devices also have a color chart that you can reference to determine the exact CO2 level in your aquarium.

Most aquarium plants require about ten to fifteen parts per million (ppm) of CO2 to thrive, and higher light-demanding species need higher levels. A drop checker will help you estimate CO2 levels and monitor pH in your tank. The drop checker will suction to the bottom of your tank and use a special pH indicator to indicate the level of CO2. The liquid will be blue at first, but will gradually turn green. If the coloration reaches thirty parts per million (ppm), your CO2 level is within the acceptable range. On the other hand, if it is yellow, the CO2 level in your tank is unsafe.

The CO2 drop checker is made up of a glass drop checker, a suction cup, and a 60ml bottle of 4dKH/pH reagent solution. It has a user-friendly interface and gives you a reliable reading in two hours. It is also made of stainless steel and has a built-in safety valve to prevent accidental CO2 release.

Incorrect indicator solution

If you are using a co2 drop checker and the drop checker is not changing colour, you need to add the correct indicator solution. The solution should contain a KH standard or four degrees KH (4 dKH) and a pH indicator. It is important to fill the drop checker upside down before you add the 4 dKH. You can use a syringe to do this. Once you have added the 4 dKH, you can add the pH indicator. The indicator changes colour based on the concentration of the gas.

Make sure that you have distilled or RO water to clean the drop checker. Do not use soap or detergent to clean the drop checker, as this will affect the results. If you are unsure of what the correct indicator solution is, check the user's guide or the manufacturer's website. Some manufacturers provide a solution pre-made with 4 dkH.

Make sure that the indicator solution is in a visible spot so that the aquarium owner can observe it. In this way, they can see if the color of the indicator solution is changing against a solid white background. Unlike a water tank, a drop checker is a reservoir of indicator solution and has a small amount of airspace that helps avoid direct contact between it and the aquarium water.

Slow response

When using a CO2 drop checker, you need to be aware of the different factors that affect its performance. In particular, you need to watch for dead zones. If the drop checker is placed in a dead zone, it will not be able to give you accurate readings. Also, drop checkers require some time to reach equilibrium, which varies depending on the design and other conditions. In general, you should allow at least three hours for your Co2 drop checker to reach its equilibrium.

If your CO2 drop checker is too slow, there is a possibility that your tank is not receiving enough CO2 at all. In such cases, you need to increase the amount of CO2 that you give your tank. In larger tanks, you may have to use higher CO2 rates.

Alternatively, you may have to adjust your circulation and reposition the CO2 diffuser. This will aid in the diffusion process and help keep bubbles in the water for a longer period of time. In any case, the CO2 drop checker should be adjusted in small increments until it reaches a green reading. However, it is important not to overdo it or you could gas your fish.

Need to change fluid more often

The CO2 drop checker is a great tool to use when monitoring CO2 levels in a tank. It uses a simple method that requires only a few drops of indicator liquid to measure CO2 levels. You should replace the indicator fluid about every four to six weeks, or as needed, or if the color starts to fade.

A drop checker's colour change response can be slow for a variety of legitimate reasons. For one thing, it only measures the CO2 concentration for an hour or two ago. It may take up to four or five hours for the CO2 concentration to reach equilibrium. It may also take a few hours to change the bubble rate.

In market, there are some low cost co2 indicator liquid, which color change sensitive is not good, it will maybe give you a wrong indication and cause your fish, shrimp, snails die as lack of air. Choose UUIDEAR co2 drop checker and liquid, will be safety for your aquarium tank!
