Yes, he did.
From what I understand: Aquasoil performed as well as lake sediment and not as well as a combination of garden variety potting soil and sand. Of the 6substrates he studied, ADA AS Amazonia ranked 5th overall.
He found that enriched substrates outperformed inert substrates, but he did mention that a better test would have been to test Aquasoil with minimal water column dosing.
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.
