    Gray mottling on sunstone pearl cove blue

    Pool was completed in April 2015. Nice day for plastering with daytime temperatures in the 70's. Finish looked very consistent in color for the first few months after which we left the area and returned this September.

    Now 5 months later the finish has a mottled appearance, especially in the deeper water. I don't notice any mottling in the spa or on the sun shelf. Then when the sun comes out it pretty much disappears.

    Could you post some test results please? Do you ever use algaecide or do you use any kind of mineral system or alternative sanitizer?
