The presence of tannins is one cause of brown or yellow water that is usually not a problem. Tannins are present in driftwood, and over time they will leach into the aquarium water, staining it yellow to brown. Tannins lower the pH of the water and soften it. For some fish, this may be desirable and even recommended.
