Thank
thank you for his info! I was mainly worried about the fish and plants health. Glad to know it won't affect them.Not my own words but is most relevant for you: Eventually with water changes there will be less and less tannins. It does not harm your tank or fish. Some folks actually like the look.
Tannins are a natural compound contained in the driftwood and they are released into your tank water as the driftwood soaks. Tannins will stain your tank water a light yellow color or when concentrated - the color of tea. The amount of staining depends on what type of driftwood and how much wood driftwood you are using. Boiling driftwood can be thought of as placing a bag of tea in a hot cup of water. The longer the tea is in the water and the hotter the water is, the more tannins that will be released.
