The diffuser works very well in my 120L tank. Plant growth has improved noticeably since I installed it. The ceramic membrane is easy to replace and the acrylic body is durable. No leaks or issues so far.

I switched from a standard diffuser to the CO2 Art IO model. The CO2 absorption is much more efficient. My plants are thriving, and I don’t see as much CO2 waste. The small size fits perfectly in my tank.

Great product for larger tanks too. The large version handles my 200L aquarium well. The ceramic membrane lasts longer than the previous one I used. Easy to maintain and very reliable.
