how 2 keep ducks pond clean...
I have a fairly small pond for my ducks,now that the winter is coming I had to take the hose out,so it doesn't freeze. I used to keep the hose in dripping and the water stayed SO clean,never smelled. Now it smells,and it looks so dirty,they still go in but is it ok?
After winter,how do I get it back to it's clean self again? It will freeze,our winters get to -25 below freezing sometimes. Any suggestions?
