On the API,when pH sample is dark blue that's all it will do, your "high" pH test is good.
pH looks to be 7.8-8, that's good..
Looks like 7.5-8 on the LaMotte.
I wouldn't worry about alkalinity just yet.
Just my experience here, but when pH is over 7.5, alkalinity seems to be acceptable in most cases. I'm sure there are exceptions but this is a brand new pond and there will be some differing numbers (up-down) and when it stabilizes in the first full summer, action can be taken to move or adjust slightly.
