Greetings, I have a Low-tech 10 gallon planted Betta tank and am looking for a way to boost CO2. I have read a lot pertaining to using CO2 bells and realize that this will not be as good as a pressurized system. Basically, it is a inverted plastic bell stuck on the glass with suction cups. Some say it works and some say it does not, but they usually have bigger tanks. I just want a little CO2 supplement for the plants and am not really interested in going 30 ppm.
So, has anyone ever used passive CO2 before? What was your experience?
