Tracks Nitrogen and pH, giving a graphical chart to visualize the changes as the tank cycles. Change only the first date, the rest are keyed to it and will follow automatically. Enjoy!
Nice set up with excel. Doesnt work for me though as my parameters have been stable for near a year. Looks like it could be fun to watch the bar graph change as a tank cycles. A user will have to have microsoft excel on thier computer though.
