Best micro co2 on the market

Anthony · March 4, 2026

This is not only my first time with shrimp, but also with CO2.

The micro is a learning curve for me. As mentioned before I somehow lost the pressure with the original cylender I bought 5 more and used a soapy water solution in a spray bottle to help me with the second and it did well for I believe three days , and tonight while working over the setup to put some additional plants in the bowl. I turned around and looked and guess what the second little cylender was empty. Now from what has been said, they should last at the very least two months. I have it set for about one bubble every second. Well it the second of my five bottles is on it now. I will see if I could have bumped the little adjustment knob and ran it out fast, I dont know. Doest seem as if my little shrimp was affected by a load of too much CO2 going in the little bowl.
