True, but if the fish are stressed, it's better to clear it up. DarkHive's Tetras might not be used to it yet.

Tannins are natural, but the pH shift could be bothering your fish. What's your current pH? Driftwood can lower it over time. If it's below 6.5, consider adding crushed coral to buffer it.


Good point. Also, how often are you doing water changes? More frequent changes can help clear the tannins ...
