clay pot disintegrated- water quality?
I have an established container made from a stock tank (about 250 gallons, I believe). A painted glazed piece of terracotta pottery that was in the pond froze over the winter, and the glaze cracked off, exposing the clay of the pot. Now the pond water is very red/orange, almost rusty looking, but I think it's probably due to the clay from the pottery. Will this negatively affect the water quality of the pond? The fish seem to be okay, although they're not very active yet since it's so early in the spring. Do I need to do a complete water change?
