Mosaic installation pool?

Question:Is stone or marble mosaic suitable for pools and can it interact with chlorine and other chemicals?

Answers:
It's perfectly fine if treated and sealed.

You can maintain the life of such materials by maintaining a proper balance on the chemicals in the water. Having corrosive water (unbalanced on the low end) will leech calcium from any materials containing it (tile, marble, grout, concrete, plaster, etc etc). This is easily overcome by supplying the pool with adequate calcium in the form of calcium chloride (a calcium hardness increaser).
