Tom-

I've had a low tech tank for decades so I'm ready to go hi tech. I want to grow some of those difficult plants I've always dreamed of having in my tank. I WILL learn this. I am highly motivated. I'm sure I will make mistakes in my learning curve. I appreciate all the advice and work you have done for others in the hobby. People like me depend upon all the knowledge you all have accumulated.

I am going to use the EI method. Loved Greg Watson's dosing guide! His statement that we don't all have to be chemists took a lot of weight off my shoulders!

One question for me still remains.... I dosed Flourish Excell yesterday to help with my BBA outbreak. When should I dose again? My CO2 is at green (drop checker).

Also, if I may..... You state that GH should 17-40ppm but mine is 5.59. I thought I already had pretty hard water. You say to add GH booster at a water change. I thought the CSM+B was providing the trace minerals. Do I just need more Calcium and Magnesium which the GH booster provides?
