I don't mean to butt in but! What type of plants are you going to be feeding CO2 to? If you have low tech plants then one DIY CO2 bottle will be fine. If you have faster growing plants and strong light then I would go with another bottle. I would not listen to the last post that you need multiple. 2 DIY will put you in the proper CO2 range even at heavily planted from personal experience since I have this same tank. CO2 isn't something that should be played with as you can and will most likely gas your fish. DIY are unstable, unpredictable. With no PH controller you will have frequent crashes. I am to the point were I am going to shell out the money for a complete mini system.
