I was just wondering what you would recommend for adding CO2 to a 5.5 gallon tank? I am going to have 28W of light over it, and someone (actually a few someones) mentioned that if I didn't have CO2 I would probably have an algae problem. I wanted to go low-tech, but I don't want a major algae problem. :-/ Then I saw that you can get CO2 for about $20. Someone suggested:

and

with emphasis on the second one (b/c it is a small tank and not much room for the ladder). Are these good suggestions, or do you know of better?
Also, general CO2 questions:
-Can CO2 be harmful to the fish? (by not having as much O2)- I read it should be turned off at night, but as long as I do that, the fish should be OK?
-Will the extra CO2 alter the pH or any other factors? (I read that it could lower the pH, and reduce the hardness)
- Can I test how much O2 and CO2 I have? And if so, what is a good level?
Also, do you recomend fertilizer for this tank as well? (Or instead of CO2?) I've heard a lot about flourish excel. Is the general consensus that it is the best?
I know I am asking a lot, but I really want to do this right!
It is going to be a dwarf puffer tank, and he is my favorite fish (that's why he's getting his own tank rather than being returned), so I really don't want anything bad to happen to this tank.
