Thank you for the kind comments. Yes, just switched to Co2 a few days ago and to the EI fert system. Was using Excel and Flourish over the three weeks of growth but I did have a great chance to discuss with Tom Barr my system and he suggested I read all I could about Co2 (as I was apprehensive) and make the leap. Goodness..I am glad I did.
The system I decided on is a GLA Ultimate Co2 System with a 15 # cylinder. Added the Oracle Drop Checker. So to help with my learning curve -fail safe wise the tank has a bubble counter, drop checker and a ph controller. Also I am able to watch the fish VERY closely as they are in my office only 6 feet away.
