They released lots of Co2 but released it extremely quick so not really good for my requirements of adding Co2 to a grow room for hot chillys and various herbs it just got pulled out with the air exchanger in a matter of minutes where I needed it to be a more steady stream of bubbles, not its intended use I no but hoped it would be a cheap alternative to an expensive Co2 generator.

Me gusta: La facilidad de uso y eficacia. Se lo meto en el bote de JBL con un poco de agua y veo como van saliendo despacio las burbujas de co2, en caso de tener alguna urgencia. Por olvido de echarlo, etc.No me gusta: De momento ninguna queja.Lo tengo para urgencias para cuando se me olvida rellenar el CO2, le meto la pastilla en el bote de JBL y es una maravilla. No me ha defraudado nunca. Lo seguiré comprando

Many people say that carbon dioxide ingots are useless! I doubt it, but it's a German sera product and I'm trying to buy and use it. Because it is a famous brand of a big factory, it will not be produced casually. I want to talk about products; The dosage on the instruction manual! If you use it according to it, you will lose your expectations. Let's put it this way! I take my pills, but I don't have a CO2 monitor! Therefore, it is not clear whether the carbon dioxide in the fish tank is present or sufficient, or how it exists!This time I use the monitor, and I can see that it is blue liquid! Verify that there is no carbon dioxide in the fish tank, even the pills put in earlier! I'll put a piece first and pay attention to the change of the monitor. It didn't change at first, but after a while, I noticed that the liquid in the monitor changed slightly from dark blue! I suspected I was wrong, I suspected ❓ in my heart, so I put the second tag in, but I couldn't help putting the third tag in! At first, nothing seems to have changed! However, after a while, I didn't look, looked at the monitor again, and found that it turned green! Yes, it's definitely green! Pay attention to the monitor in the photo. There is no water in the blue pipe, but there is water in the green pipe! Verify that the carbon dioxide gas in the fish tank has entered the monitor!The problem is, according to the factory dose, it is not necessarily correct! And it depends on whether you use it every day or every other day or two! I use 40-60 liters of water to calculate, a bottle has 20 carbon dioxide ingots, how many bottles should I buy in that month! If you don't use it every day, pay attention! I didn't notice when the monitor fluid turned blue. Therefore, we have to measure the dose and whether to use it every day! With the extension of light irradiation time, whether to invest a certain dose and wait for a period of time before starting light irradiation time! This should be observed by oneself, how to control it! I can say for sure that this carbon dioxide ingot is effective!
