Hi All,
I put a batch of koi in my mud pond three week ago, I believe this to be correct. I have noticed a difference in the koi's color, or a least it looks that way to me. The hi and sumi looks brighter, the sumi is getting very black, and the shine is so much better on the koi. Jack say he does not see the difference, but he does not really pay that much attention to the koi, I on the other hand pay very close attention to them, so if one gets sick on me I can Qt the koi and maybe help it. I cant really tell about the shiro, that may be due to the water turning green. I checked the ph and it is 8.0, it is to my understanding that this has something to do with the color of koi, I dont know, all I know is I swear, they are changing on me. My showas orange is a lot deeper than it was and the sumi is very good. Whats going on you all, can you give me some insite on this. Is it the mud that is doing this?

They dig in it all the time.
