The sooner we can establish you water quality, the sooner we can offer some helpful advice.
Please post your numerical water test results.

Please see a readout of the pond water.we are in the process of doing a 50% change and all the filters are currently off. We have put tap water treatment in

Wow, you do not have good water quality.
No wonder your fish are suffering.
Nitrates are way too high, GH is high, not as serious.
Nitrites should not be registering anything.
What are the test results from your source water? (it's important)

Please post a picture of your whole pond. There is something not right here.

This is a 700 gallon pond with 8 large koi and 7 goldfish - way too many fish!

Did I miss an ammonia reading?

No, I don't see one either.
