Description
Description
The Me CO2 Check Glass is a glass drop checker for planted aquariums. It holds a small amount of indicator liquid that changes colour with the CO2 level in the water, and it comes with 15 ml of Me CO2 Check Liquid.
Bubble counts tell you how much CO2 goes in, not how much stays in the water. A drop checker shows the result directly, so you can raise CO2 for plant growth without guessing and without risking your fish.

How to read the colours
- Blue: too little CO2. Increase the bubble rate slightly.
- Green: target range for most planted tanks.
- Yellow: too much CO2. Reduce the rate and watch your fish.
How to use it
- Fill the checker with a few drops of indicator liquid.
- Attach it with the suction cup in the lower half of the tank, away from the diffuser's bubbles.
- Wait about 1–2 hours after each change before reading, because the liquid reacts with a delay.
- Refresh the liquid every few weeks or when the colour stops responding.

Frequently asked questions
Why is my drop checker still blue with CO2 running?
The reading lags by 1–2 hours. Check it around the middle of the light period, not right after CO2 switches on.
Can I use it with a DIY or cartridge CO2 system?
Yes. It measures CO2 in the water, whatever the source.
Pair it with the Me CO2 Regulator Ultra for a complete pressurised setup.
