One of my biggest challenges of keeping koi and plants in the same pond involves the turbity of the water. The koi root in the waterlilies and keep the water murky. Over the years I have tried one of my hair brained ideas after another. Using tomato cages in the pots, netting off the the plant area. cover the top of the pots with chicken wire (the worst) & of course this season's idea, which I will reveal at a later date. As I was surfing the web looking for ideas, I came upon the article linked to below. It is the best information I have found on koi and water quality in ponds.
