IME, the current version of ADA Aqua Soil cycles in about a week with an established filter and a decent amount of plants. Even though ADA and many aquarists recommend frequent water changes during cycles, I do without and let the plants do the work.
Bump: the second generation AS broke down into mud after 2 -4 years. The versions after that seem to be more stable, as I have them going mainly intact after 4+ years.
