Glass CO2 Drop Checker – CO2 Monitor Kit for Aquarium Planted Tank CO2 System (Drop Checker with Solution)

I like the fact that this drop checker is of a different design compared to the regular style. It’s made of good material and is nice to look at. One drawback is that it takes more solution to fill to level that’s recommended but it’s a lot easier to fill compared to the other designs. it’s been very accurate thus far on my CO2 levels so I’m happy with it.

works great. I also have a ph meter it seems to do a good job tracking along with the meter

Le coloco 4 estrellas ⭐ sólo porque no trae un manual del fabricante en donde se indique si es con mezcla o como usarlo. Tuve que remitirme a la descripción del producto, teniendo en cuenta que cada Drop Checker, se maneja diferente. Sin embargo, el producto tiene un aspecto muy bonito visualmente, trae 2 ventosas para su anclaje. Lo acabe de poner iniciando con un sistema de CO2, ya solo me queda esperar y ver cuando cambia del color azul, lleva par de horas y por el momento no lo ha hecho ya queda esperar.

Works as described. No issues

The color was blue when I dripped it from the bottle, and it remained blue in the fish tank. I measured the PH level using a digital device, and it did not correspond to the blue color. I believe there is an expiration date on the liqued, which the seller did not mention on the box. The glass is perfect.

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.

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.

Excelente producto, muy buena calidad de materiales
