Some aquarium plants can obtain the needed carbon from carbonates, but the process is not efficient, and only a few plants can do it. But, this doesn't mean you must inject CO2, since there will be some amount of CO2 dissolving into the water from the air. With higher light levels, plants will need far more CO2 than the 3-4ppm present without CO2 injection. So in those cases, CO2 injection is necessary. But even at lower light levels, CO2 injection will improve plant growth. Chuck Gadd http://www.csd.net/~cgadd/aqua |

But the question you should be asking or may have meant to ask is "Do all planted aquariums have to have additional CO2 for the plants to grow?". The answer to that question is no. Semper Fi!

Actually yes they do, but no you don't have to ADD CO2 which is what Victor
meant.. Normal CO2 level in a tank is around 3 - 4 %. Lots of plants will grow well at that level with low light levels. Bob "Victor M. Martinez" wrote in message ... No. -- Victor M. Martinez http://www.che.utexas.edu/~martiv |
