Shusui, asagi, midori, kikusui etc all respond negatively by darking with hard water. to reverse soften it....to learn more about softening water get onto the worldwide web and go to Yume koi's site and read mike's explaination from a number of interesting articles he's written and been published in various koi magazines.His information and influence caused me to purchase and use reverse osmosis water to the benefit of my asagi's. lot's to learn lil helper...the more of which you absorb the more you realize is out there...at least your starting early in life!

So shusui, asagi, midorigoi, and much more. They are all negatively impacted by hard water.
Hmm..
So I am guessing probably some of the gosanke are positively impacted by harder water, I cant really guess.
You said Yume koi.
hmm, is it www.Yumekoi.com?
There is so much I dont know, and probably a good portion I never will. but then sometimes I think that the koi hobby really only became bloomed for about 40-60 years.
I can expect more to happen in the future.
