Some call it the biological cycle, the nitrification process, new tank syndrome or even the start-up cycle. They all are referring to the same cycle - The Nitrogen Cycle. The aquarium nitrogen cycle is a very important process for the establishment of beneficial bacteria in the aquarium and in the filter media that will help in the conversion of ammonia to nitrite and then the conversion of nitrite to nitrates. Check out the aquarium water chemistry page (on the left) for more information on these terms.
A practical approach to freshwater aquarium water chemistry
Injecting carbon dioxide is yet another way of lowering the pH-value, but it can cause a lot of problems unless you know exactly what you are doing. I therefore recommend you to read a more in-depth article about CO2 and water chemistry before you go about. CO2 injections will lower the pH-value without simultaneously increasing acidity; hence produce an unstable situation in the aquarium. You will for instance have to be careful with water changes, since the new water will have a high pH-value compared to the aquarium water unless you inject CO2 into the replacement water as well. CO2 does however have its upsides; it will for instance promote lush plant growth (provided that your plants receive sufficient amounts of nutrients and strong light).
