If you own a pool, you‘ve probably heard the term “scale“ used in reference to the condition of your water. But what is scale, exactly?

Scale is a build-up of minerals on the surface of your pool.

It can be caused by a number of things, including:

– Hard water: This is water that contains high levels of minerals like calcium and magnesium. When it evaporates, these minerals are left behind and can build up on surfaces like your pool‘s walls and floor.

– Poor circulation: If your pool doesn‘t have good circulation, the water can become stagnant and start to form scale.

– insufficient pH: If your pool‘s pH is too low, it can create an environment that‘s conducive to scale formation.
