I just tested my water and I got a water hardness indication that was
high. What do I need to soften the water?

Okay, here is where I'm going to pass you along to the experts,
and I do mean experts ;-)
Experts, there has already been one koi death, four other newly purchased koi
in the pond, 20 goldfish and 10 minnow types.
I've retitled the thread.

Post your pond size again so they can figure out
how many gallons you have.

And then post what the reading was on your test.
