Organic Staining and Tannins

Water can become discolored and stains can occur even if metals are not involved. In this episode, Eric talks about organic staining and discoloration, thanks to Tannins. They're relatively easy to manage if you regularly clean organic material out of your pool (leaves, pine needles, acorns, berries, etc.). If you let decaying organics stay in your pool or on your mesh safety cover, tannins can be a real problem.
