This is a quality product. The size of the CO2 bubbles generated is finer that the previous glass diffuser I had. Do not have the risk of breakage which cleaning the tank, as the body is of plastic. Overall a good buy.
I stand corrected. It's works awesome .Mine took little bit more time (5 days submerged in water). But it works just like atomic diffuser even with DIY co2 for my tank.
Good product, we need to sock this product for 24hrs to get good results
