CO2 questions.

Eshnon

I have a 20 gallon planted tank that has plants with browning leaves... Also a plant that somewhat needs CO2.. regardless of the situation, getting CO2 is what I was planning on getting anyways. However, I dont know what I should get... Petco/petsmart have a CO2 system with a fermentation chamber.. and is by far the cheapest that I've found. I just wanted to know if anyone has used this system and if it's any good. If someone has a cheaper or a better system that is cheap to maintain.. please feel free to share!

If your going to go with yeast then its far better to just DIY your own system. Google "DIY yeast CO2 reactor" for info.

Browning leaves can be related to any one of several nutrient issues and/or light. Before you jump into adding another level of balance and maintenance which carries other issues that will need to be addressed too, I would first review the current system in case something is lacking or out of balance.
