JARDLI Small CO2 Drop Checker

Love this thing. Looks cool, great size for my 29 gallon. Easy to set up, need to get another one for my other tanks

This is great super easy to fill and see in the tank

Works great. Unfortunately i found one of my loaches inside and passed.

It’s ok

These are great. I like the circle design as it’s more unique. The drop checker works perfectly and is well made. I made it clap on a handstand out of pure joy at how much I enjoy this 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.

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.

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