as the previous post suggested... it is just various types of algae.. unless it really bothers you, i dont see why you need to remove it.. or at least not every bit of it.. it will just keep growing back anyway.. i like algae growth in my tank, makes it look more natural... although the brown algae could be a sign that you have an excess of nutrients in the tank.. in fish tanks that is usually and indication of overfeeding, overcrowding or not changing the water enough.. i wouldnt worry about it too much though, turtles are pretty messy eaters, so i wouldnt be surprised if the algae is just sucking up the nutrients from food that hes chomped to bits ...
