Thanks Lynn!


I have my glass diffuser near the bottom of the tank, under the HOB outflow, so as the bubbles rise, they get dispersed around the tank. As long as I keep the water level high, the surface agitation isn't very much. I imagine some of the CO2 is lost, but as long as I keep the bubble rate at about 1 bubble/sec, the CO2 levels are good (confirmed 30+ppm w/ drop checker). These 88g cartridges only last about 2 weeks for me, so I'm currently looking for an adapter so I can use the 20oz tanks, which should last around 3 months and are refillable.
