Tom acknowledged that while the ADA AS came in 5th it was under more controlled conditions with zero water column fertilization and much harder water. He still recommends AS+EI(lean or othewise) as being the best combo and not as messy as soil.

Homer_Simpson is correct, Tom finished the experiment. The conclusion can be found on his site. It made for some interesting reading.
