Question
I'm doing a science fair project on The Effects of CO2 on the Growth of Corral, and I was having problems with how to put the CO2 in the water. Do you know a cost-effective way to raise the CO2 in an aquarium, while not affecting other variables? Also, what would be the best way to measure growth in corral? Thanks a lot.

Answer
Hi Keith
It seems that you have a couple of problems here.  The growth of corral is extremely slow so I do not know how you can measure it.  As to the CO2 you could always bubble it into the water.
 I think you may have to approach this from a research standpoint and look up some literature on the topic.
