My thought was that adding CO2 to the air bubbler would increase its partial
pressure enuf so instead of stripping out the CO2, the bubbles would add
insignificant amounts of CO2 to the water. Then, being heavier than air, the
CO2 would collect between the water surface and the glass top and slowly be
absorbed. I could be way off base with this.
Do you think my power filter would suck hard enough to power the sponge
filter? The power filter is rated 100 g.p.h., and says it can be used to
power an undergravel filter.
