The Walstad method does not include adding fertilizers or CO2. If you want to use that method it will be most likely to succeed if you follow all of her directions as described in her book. If you want to get faster plant growth, with quite a lot more tank maintenance, you could be on the right track, but I suspect you have too much light for the amount of CO2 you are using, because of having the lights only about 8 inches from the substrate. It would help, based on my experience, to also use Excel or Metricide, at 2 ml per 10 gallons of water, dosed every day.
