Review on Enhance Your Aquarium with the Yosoo DIY CO2 System Kit Pro for Planted Tanks – Includes Tube, Valve, Gauge, and Bottle D201 by Claudia Brown

The hardest part was finding some soda bottles (I don't usually drink soda) lol. Installation was easy. I washed two bottles, pouring citric acid (a mixture of water with water) into one and baking soda and water into the other. I pressed HARD several times to get it to work and it's been happening on its own ever since. Initially the pressure on the manometer was in the lower part of the green zone (1kg/cm3). It worked. It took several days to drip 1 bpm and the pressure slowly built up to the top of the green zone (2 kg/cm3) and bpm was slightly higher. Now it fluctuates a little on its own, as does the speed of the bubbles. It's ok, I just want some CO2 in my tank, I don't want the perfect stable 30ppm. I'm actually happy to keep it lower like I do with liquid enzymes.
