The result of the test seems fine, it looks like the water is pH 8, which would be optimal. But yes, you should test at different times of the day because the pH can actually fluctuate quite dramatically because of other factors. Run the tests again, go for a digital tester if you want more accurate results, there are plenty here https://www.optimainstitute.com/water/alkalinity-tester.html. As when it comes to water clarity, did you add too many nutrients into the water? This can be a problem at times and cause the pond water to get weirdly colored.
