Calcium in the right amounts is essential not only to the human body but also in things such as hot tubs. To keep the pH levels of water in a hot tub balanced, calcium is necessary. However, too low or too high amounts of calcium in hot tub can destroy it and even affect your health.
Generally, hot tubs must have a pH balance that ranges from 7.2 to 7.8 and calcium hardness ranging from 80 to 200 ppm. In this article, we will explore more about calcium hardness and how to measure it in hot tubs.
Understanding Calcium Hardness
Calcium hardness can make water hard or soft. When there is an increase in calcium levels, the water will become and feel hard. On the other hand, when the calcium levels are low, the water will feel soft. That is why water is said to be either hard or soft.
If you immerse yourself in hard water, chances are your skin will get dry and itchy. Contrastingly, submerging yourself in soft water will give you a slimy feeling.
In simple terms, calcium hardness refers to the amounts of calcium you can measure in water. For a hot tub to be clean and safe, the water in it must have the correct levels of calcium.
Below are some effects of incorrect levels of calcium hardness in water:
Low calcium levels can cause corroding of the cement or plaster around your tub. This happens when water starts eating the materials of your hot tub to get the calcium it needs.
High levels of calcium in water can cause scaling or calcium buildup on your hot tub. As a result, you will experience clogging and plumbing issues. Note that calcium deposits can be challenging to remove.
- Eye and Skin Irritation
High levels of calcium hardness can affect the pH levels, causing dryness on the eyes and skin. Consequently, this can irritate.
How to Measure Calcium Hardness in Your Hot Tub
It is recommended to test the calcium hardness in your hot tub monthly or every time you change its water. To do this, you need a test strip, which you can purchase at pool supply shops or hardware stores.
When measuring the amount of calcium water, it is crucial to first know the volume of water you will check. When you have the correct measurement of water in your tub as determined in the strip, dip it into the hot tub without moving the water. Also, you must know the exact time to check the results by reading the strip label. Then, refer to the legend stated in the kit.
How to Balance Calcium Hardness in Your Hot Tub
If the calcium levels are high, there are steps that you can take to lower them. Below are ways on how to lower calcium hardness in hot tub:
- When Calcium Level as a Little Beyond the Average Level
In this case, you need to drain a bit of water from the tub. Then, add some fresh water and a product that can control scaling to keep the levels normal. Put in scale control every week and always and follow the instructions on how to use the product.
- When Calcium Level is Too High
When calcium hardness is too high, then you must completely drain your hot tub. After cleaning it, refill it using a water hose filter to keep some minerals out. Then, use a scale control to balance calcium levels.
On the other hand, you are probably wondering how to raise calcium hardness in hot tub. The best way to increase calcium levels in your hot tub is to add some calcium to its water, specifically calcium chloride.
Knowing the calcium hardness of your hot tub is essential to keep it safe and in its best condition. Also, it is crucial to purchase the best hot tubs in the market to ensure quality and durability.
