Low alkalinity is the more serious of the two extremes. It can cause rapid fluctuations in pH, because the water can’t as easily counteract the effects of acids, like acid rain or naturally occurring minerals. Such an environment has a cascade of effects on your hot tub’s appearance: it can damage and erode its surfaces, while also corroding metal parts, a perfect storm can result in unsightly stains. Low-alkaline water also won’t be able to balance the amount of phosphates, which feed algae, resulting in water that is green.
