Does water hardness affect alkalinity?
Alkalinity and hardness values are normally similar to magnitude because calcium, magnesium, bicarbonate, and carbonate ions in water are derived in equivalent quantities from the solution of limestone in geological deposits. However, in some waters alkalinity may exceed its hardness and vice versa.
What happens if calcium hardness is low in pool?
Low calcium levels will ruin your pool’s alkalinity. This will, in turn, corrode metal items. Your pool’s railing and mechanical parts could become damaged. Thankfully, it’s easier to raise water hardness than lower it.
Should I worry about calcium hardness in my vinyl pool?
