SamanthaSamantha: Super simple and easy to install and to figure out your CO2 levels. There's three colors that determine your CO2 level that associates with the amount in your tank.. I did write that on the bottle, because it isn't on there and I did not want to keep the box or the instructions.. So I just wrote down the colors and what they meant on the bottle.

Amazon Customer: I had a plastic one that kept leaking, this one is great! It's been weeks and no missing indicator fluid!

Aaron D.: I really needed something to help monitor CO2 levels in my planted tank since I added some Chili Rasboras and this one had good reviews so I decided to give it a shot. I have a little bit of regret. I knew that the reagent would have a few hour reaction time, but it takes at least 6 hours for mine to register changes. For instance I reduced my CO2 BPS on Saturday evening and finally on Sunday evening the indicator had started to show more of a bluish color. I've been using it for around 10 days and have yet to be able to dial in my CO2 because it takes SO LONG for the changes to level out and register.

Also, and I swear I'm not color blind, I find it incredibly difficult to differentiate a green color when it fades out of blue - it seems to become extremely translucent and any hint of green starts to look yellow. I have never seen anything resembling the rich green color on the side of the bottle even as it passes from blue to yellow.

Finally, it arrived with what seems like hard water buildup inside so I'm not certain it's even new.

Overall I think it might be better to spend slightly more money.

Bobby Magic: This Glass Co2 drop checker is a valuable tool to have in your tank. It's small and being glass it basically disappears in the tank and is NOT conspicuous. The monitor fluid goes from blue to green when the CO2 levels are proper and with a planted tank now that drop checker REALLY disappears! The drop checker has helped me several times as I was injecting too much CO2 so the green went yellow and even to clear once. I shut my CO2 generator down a day or two and the monitoring fluid went back to green and I turned the CO2 generator back on turning that needle valve down to about one bubble per second. Finally I got the needle valve to where the drop checker was green every day which is where you want to be. Do you ABSOLUTELY need this? No. But for me, it was quite helpful and I'm glad i bought it. Glad I'm using it. On a side note, I notice that in photos of a lot of really high-end Amano type tanks I see these little CO2 drop checkers so I figure if THEY are using them perhaps it would be wise that I use them as well.

Sundragon: Update: 2022-12-14: I got two replacement suction cups - This means I don't have to toss the drop checker. It's back in the tank and working perfectly. FYI, trying to use heat with the old suction cup doesn't work. Just ask for a replacement. Their customer service is great!

Update: 2022-12-08: I wrote support and they are sending me a replacement suction cup! If you need a replacement, reach out to them.

I think it's a good piece of glass - and works... I mean it's just glass, so why wouldn't it. Three years later the suction cup is hard as a brick and useless and it won't adhere to the side of the tank. Using a little silicone lubricant doesn't help even if the glass has been cleaned. Ideally, we'd be able to buy suction cups to keep using this vs making it a disposable object that adds to the planet's trash and makes us spend more.
