We are planning to build a sw in ground, lagoon shaped pool atapproximately 20k - 23k gallons. Our back patio has a courtyard with fireplaceand pergola. The look is old New Orleans with used brick. I have heard some talkthat suggest brick around the salt water would be a problem. Anyone with brick around sw? Any problems? I found a product that looks like used brick but is a new fired brick. All info and pictures are appreciated.
