You have a beautiful pool, Yomanda. As for acid staining, one feature that I like is the final color does not have be even, and can be a combination of colors. We had the PB replace a portion of our driveway, and we would test the stain on it, before using on the pool deck. We are hesitant to put down a topping, and that is one reason acid staining seems appealing. Thanks for your input.
