just curious.... air stones
i was just thinking, ive been told many times about not using any air stones or air devices in planted tanks, especially with co2. now the co2 part i understand...
but wouldnt a non-co2 injected aquarium be ultimately unaffected by air devices? i understand that the plants consume co2 and expel o2, and fish the opposite... but if i had an air device creating a large increase in surface area for gas exchange, wouldnt i exchange just as much o2 as co2? it would be a wash, no?
