After about a week of running my DIY CO2 injector on my freshwater tank I've decided I need more plants and more light, I'm really inspired by Takashi Amano's work. The pH has leveled off at about 7.1, nearly where I wanted it. I have a kH test kit on the way to check out my water hardness, it's a good thing to know when messing with CO2. Since my 2 liter CO2 yeast generator is already starting to fizzle out I'll add another bottle in the setup and post some pictures when I finish. Also on the way is a Pollen Glass to diffuse the CO2 into the water a bit better. Currently I have 15W of light from the AllGlass florescent fixture I've had forever, I really want to upgrade this to get around 40W or a bit more. With that amount of light I should be able to grow anything. I only have Anubias Bateri tied to the rocks right now until I get the lighting and CO2 stable. I'll keep you posted.
