Need help for High Range PH, it is only 7.4-7.6

After I find out my High Range is too low, Just did a sand clean up and water change, three green chromis should be gone, 6lines, and Salifin Tang, those are in the buckets with most of live rock and coral, the main tank have blue tang, 6 clowns, bi-color angels, and Lawnmower Blenny, what I need to bring the the PH.

How much water circulation do you have?

That are the Alkalinity, Calcium, Magnesium, Temperature, and Salinity?

What time of day was the test taken? What are the PH ranges at other times of day?

What type of filtration do you have?
