I don't think the charcoal will release the so called goodness out in one go, cause based on what I read from ADA Japan's website, the NA carbon or the bamboo charcoal will act as biological filtration in their Super Jet series overtime. Hence I feel what member Evo is doing, is perfectly fine. Amano also state that there need to exist circulation in the subtrate for the plants to grow well, thats why he had come out with the Power Sand Series.
