Sulfuric acid application for cooling water treatment

Hi everyone.

I have a question about Sulfuric acid application for cooling water treatment at Power plant. 

Owner wants to dose sulfuric acid for scale inhibition according to pH. But I am going to apply for each corrosion and scale inhibitor for cooling water treatment. 

I thought each sulfuric acid and scale inhibitor has same performance so i said to owner sulfuric acid dosing is absolutely not needed and water quality(pH) is 7.2 provided from site LAB.

However my opinion was rejected.

As replied by owner, is sulfuric acid dosing necessary?

If sulfuric acid dosing is not necessary, how to persuade and explain about that.
