Funcional para medir cantidad de CO2. Peso el kit de cristal con solución y se siente de muy buena calidad.

I have just started using CO2 for my aquarium plants. In order to maintain the proper concentration until I get enough experience to 'read' my plants directly I am using the CO2 Drop Checker. So far it is behaving well and I expect it will continue to do so.

La ventosa me llegó defectuosa, no dura ni un minuto pegada al cristal, en cuanto al indicador no veo que cambie el color a verde tal vez le entró agua las veces que se me cayó deberian arreglar ese problema veo otros usuarios tambien reportan la ventosa defectuosa

Glad to have this in my 5th tank which I just set up as a med-flow plant sanctuary. Easy to use but the instructions need work. They say nothing of how many drops of either the solution or the tank water. You can look it up online easily but it is a slight nuisance that could be easily solved. Otherwise, looking forward to monitoring the new tank as it cycles.

El producto es de plástico pero se ve bien. El verdadero problema es que la soporte de succión incluida NO lo detiene. El drop checker se la pasa cayendose a pesar de que que el vidrio está limpio. No dura ni un solo día fijo en su posición. Me consta que es la soporte de succión porque en el mismo vidrio tengo el termometro con una base aún más pequeña.
