I went hi-tech when I got my dream tank (40g breeder) from my wife a few years ago. Then my cat knocked the lights in to the tank. And then my CO2 rig went funky (couldn't hold a constant pressure).
So right now I'm mid-tech. Modified EI dosing, high light, regimented Excel, high fish load. Seems to be working alright, and I dont have to worry about massive water changes every Sunday or end of tank dumps.
