Low Tech CO2 Concerns
I've got a 40 gallon planted tank full of plants, working on my fish stock...currently about 75% there. I've gotten a lot of the plants from a friend with a 40 gallon who had great success with all of them. He kept it low tech and didn't use any CO2, and I'd like to do the same.
Out of curiosity, I was reading up on CO2 and there were suggestions about increasing CO2 in a tank naturally. It never occurred to me that this could be a possibility, but would putting the filter on a timer - which would reduce the agitation of the water surface, increase the CO2 in the water? If so, would I run into any other problems?
Thanks for any advice you have.
