I do have peat – but are you sure its not because of the camera ? Some of my photoes are really dark – but its to do with how I set the camera 🙂
Of course in some tanks I might have just set up a new one which then is much clearer, such as the small fry tank, its very newly set up.
But heres a ‘brown’ picture 🙂 .. of a nagyi male chasing a dafnia
