Hi guys, I am interested in CO2 Reactors and would prefer to try one over an inline diffuser on my first high tech setup. My concerns are noise and bubbles. I would like it as close to silent as possible with no visible bubbles in the water column. Is this achievable? What is the best style of reactor to achieve this? Is there a good pre-made option with these attributes? Where is a descent guide available on the science behind these and DIY designs/plans? Thanks guys👍.
