- Foaming: When calcium hardness is too low, it can cause foam to form on the surface of the water, which can be unpleasant for spa users.
So, how can you tell if your spa has low calcium hardness? Here are some signs to look out for:
Cloudy Water
If your spa water is cloudy and doesn’t seem to clear up, it could be a sign of low calcium hardness. When calcium hardness is too low, it can cause the water to become cloudy and hazy.
Scale Buildup
If you notice scale buildup on your spa’s surfaces, it could be a sign of low calcium hardness. Scale buildup is caused by dissolved minerals in the water, and when calcium hardness is too low, these minerals can accumulate on the spa’s surfaces.
Itchy Skin or Irritated Eyes
Low calcium hardness can cause the spa’s water to become aggressive, which can lead to itchy skin and irritated eyes for spa users. This is because the water is essentially trying to pull calcium from the spa users’ skin and eyes, which can cause discomfort.
If you notice any of these signs, it’s important to test your spa’s calcium hardness levels and take steps to correct any issues. This could involve adding calcium hardness increaser to your spa water or adjusting the water chemistry in other ways.
By keeping an eye on your spa’s calcium hardness levels and taking steps to maintain them, you can ensure that your spa stays in top condition and provides a relaxing and enjoyable experience for all who use it.
