The channel diameter is nearly twice that of similar products on the market.
- It greatly facilitates the addition of the detection liquid.
- It facilitates the diffusion of carbon dioxide gas and shortens the reaction time of the indicator solution.

- 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.
- The solution comes in a 15ml (0.5 fl oz) dropper bottle for ease of use. The solution will last 6 months if changed on a monthly basis.
Package includes
- Nano Drop Checker X1
- CO2 Indicator Solution X1
- Suction Cups X2
- Pipette X1 (for ease of filling drop checker with indicator fluid)
EXCESSIVE CO2
If the solution in the drop checker changes to yellow, then the CO2 level in the aquarium is too high.
OPTIMAL CO2
If the indicator solution is green in color, then appropriate levels of carbon dioxide exist in the aquarium, and no action is required.
INSUFFICIENT CO2
If the solution in the drop checker changes to blue, then the CO2 level in the aquarium is too low.

I'll spare you any images but despite the narrow neck, 2 separate mature fish managed to get inside the drop checker and died. It is not possible to get them out once they are in. Only use this device for fish SIGNIFICANTLY larger than the hole.

Nice looking unit but it came without the suction cup to attach it so it's basically useless until I get a suction cup.

Pay attention to the size. In a 5 gallon it’s almost comically large, but it does the job quite well as a drop checker.

Totalmente recomendado!. Es cómodo y se ajusta perfectamente con la ventosa al vidrio del acuario. Funcional y muy estético, ayuda bastante que incluyan el accesorio para extraer el líquido para los cambios del reactivo.

This co2 checker is so blue and waiting for it to turn green. Oh wait, it’s only been 12 seconds since I placed in my tank! If I come back to edit my review, this will mean that it never transitioned to green and that will not be good. Anyway, while I wait, this checker is a perfect size and was easy to fill. It looks better than the traditional co2 checkers in my opinion so I hope it works.

Much easier to use than the typical curved neck drip checkers because you don’t have the issue with the reagent getting stuck in the neck. Looks pretty good in tank and is easier to see as well.

I've got a couple of different kinds of bulb CO2 drop checkers. This one works just fine. Several folks have mentioned in their reviews that it's difficult to get the liquid out of the bulb to refresh the liquid or clean it. The simple solution is simply to use an eye dropper or pipette to remove the old liquid.As I said, it has worked fine for me and it's size doesn't seem awkward for my 20 gallon tank. Four stars because I haven't owned it long enough to give it five. Time will tell.

Lastima que no viene con el liquido para medir el CO2 y hay que comprarlo por separado, tardó un poco el pedido y cuando llegó, por no leer, tuve que esperar a que me llegara el indicador.

Most drop checkers are hard for me to fill. This was so easy. I held the drop checker at an angle, almost sideways, then opened the bottle of solution and inserted a plastic pipette to half fill the drop checker with the solution the first time. The second time I just held the drop checker at an angle, opened the flip top of the 60ml bottle of solution and filled it up half way. Faster and even easier that way. It's well made and strong. You have no glass tubes to worry about breaking off and cutting your hands. It's very easy to see the color. A lot of drop checkers come with one little flimsy suction cup that sticks to the glass about a week, then you have to buy another one in order to even use the drop checker. This one comes with 2 well made, very sturdy suction cups. I liked this JARDLI Drop Checker for $10.49 so much, I ordered a 2nd one and received it today. I just put it in my 45G high light planted tank. It can be well hidden behind plants, but I think it's so pretty I put it where it can be seen and so I can look at the solution color and know how my CO2 is doing. I'm extremely happy with this great product.

Very nice, elegant. But initially I have problem maintaining the suction cup in place. It turned out that it will only stick plemenskih on glass. If it's a plastic surface (one side of my aquarium is plastic for the internal filter system and the opposite side of my co2 difusor) it will keep falling off.A tip to make the suction cup sick better : warm it with hot water, making it softer, then sick it to the clean dried glass surface, by partially emptied the tank.Tip to fill the drop checker: use a 1ml syringe.Nonetheless, since I have a mano tank, every little space is precious to me. So, I am considering using an over the aquarium hanging drop checker (upside down U shaped) instead.
