I have not seen much information on the Aquariumplants.com CO2 regulator so I figured I would share my first impressions. The set up was straight forward the instructions were good. I do like the adjust-ability of the unit, it has great control of bubble count as well as bubble size. The light flashes every time it releases a bubble and it makes a click sound. When I put the unit inside the cabinet and closed the doors I could not hear the click. At this point I am glad I went this unit. I just wish I didnt have to make a last minute run to the store to get a roll of pipe tape so the bottle wont leak, that roll will stay in the cabinet
