Why Vegas pools scale so badly
Las Vegas tap water averages 16+ grains per gallon of hardness — that's 'very hard' on every chart. Every time water evaporates from your pool, the calcium it was carrying stays behind. Most of it deposits right at the waterline where evaporation is most active.
Left alone, that calcium hardens into a chalky white crust on glass tile and a rough scale on plaster. Once it's bonded, you can't wipe it off — it has to be bead-blasted, and that runs $400–$1,500.
The weekly habit that prevents it
A nylon-bristle brush or a magic eraser pad along the tile line, once a week, is enough to keep fresh scale from bonding. Two minutes of work saves you a four-figure repair.
Keep calcium hardness in range
Aim for 200–400 ppm calcium hardness. Higher than that and scale forms even on clean tile. The only fix is partial drain and refill — but in Vegas your fill water is so hard that you have to do this every couple of years regardless.
