A darker-colored pool naturally absorbs more of the sun's heat, reducing your heating costs. In addition, you can lower your maintenance costs by choosing a long-life pool finish. John Zita of CL Industries notes, "The cement [beneath the finish] needs to be of good quality. That's critical to the bond of the finish." CL Industries sells pre-blended finish products with proprietary additives that fortify the cement and strengthen the overall finish. Pictured here, the elegant Hydrazzo Oceana Blue finish carries a lifetime warranty.
