Hi, Depends on what's the content of the 'mud'. From what I've heard from watching a video on koi farming in Nigata, Japan, the japanese keep their koi in mud ponds for six months a year for their colour to develop beautifully. But then in Japan their 'mud' is found to be mystically suitable for koi. I don't have the scientific explanation but this is what the Japanese koi breeders do. What I learned is that green water is also good for them. Green water or algae bloom (not too excessive though as this could lead to other side effects) means that the water is healthy and nutriteous for algae (single cell plant) to grow. This also means that your bio filter is working. The nutrients for algae are the bi-product of the successful conversion of ammonia (fish waste) into nitrates. It's us human that don't agree with green water because we can't enjoy watching our koi.
