You need to soak, break up the brick, then repeatedly rinse the coco fiber. It often has a high salt content when sold in bricks. You're better off buying pre-rinsed, aged, shredded coco fiber. This form much closer approximates peat moss. It's biggest advantage over peat moss is that it breaks down slower---maintaining pore capacity---and has a closer to neutral pH. Not sure the extra expense is worth it in a planted tank imho.
