Here’s a little secret: calcium loves high pH. If your pool water’s pH is above 7.8, you’re basically rolling out a red carpet for those chalky crystals. Lower the pH to around 7.2 to 7.4 using muriatic acid or a dry acid product. Do it slowly, like you’re cooling down a hot cup of tea. Test the water after a few hours, and repeat if needed. Wear gloves and goggles—this isn’t a DIY face mask situation.

If your calcium problem is extreme—like you can write your name in the scale—consider using a flocculant. It clumps the calcium together into big, heavy flakes that sink to the bottom. Then you vacuum them out like picking up pebbles from your driveway. It’s weirdly satisfying, like watching a lava lamp settle.
