Why Pool Calcium Hardness Increaser is Necessary

As a pool owner, I have learned the hard way that maintaining proper levels of calcium hardness in my pool is crucial for its overall health and longevity. At first, I didn’t understand why my pool water was constantly cloudy and my equipment kept malfunctioning despite regular maintenance. It wasn’t until I tested the water and found out that the calcium hardness level was too low that I realized the importance of this seemingly insignificant factor.

Calcium hardness refers to the amount of dissolved calcium in the pool water. This mineral is naturally present in most water sources and can also be introduced through various chemicals used for pool maintenance. The ideal range for calcium hardness in a pool is between 200-400 parts per million (ppm). When this level falls below 200 ppm, the water becomes corrosive and can damage the pool’s surfaces, equipment, and even swimmer’s skin.

Without regular use of a pool calcium hardness increaser, maintaining proper levels can be challenging. Factors such as heavy rain, evaporation, and backwashing can lower the calcium hardness level over time. This is especially important for those with plaster or concrete pools as they are more susceptible to damage from low calcium levels.

My Buying Guide on ‘Pool Calcium Hardness Increaser’

As a pool owner, I understand the importance of maintaining proper water chemistry to keep my pool clean and safe for swimming. One essential aspect of water chemistry is the calcium hardness level. If the calcium hardness is too low, it can cause corrosion in pool equipment and surfaces. On the other hand, if it’s too high, it can lead to cloudy water and scaling. This is where a pool calcium hardness increaser comes in handy. In this buying guide, I will share my knowledge and experience on how to choose the right pool calcium hardness increaser.

What is a Pool Calcium Hardness Increaser?

A pool calcium hardness increaser is a chemical compound used to raise the calcium hardness level in swimming pools. It usually comes in granular form and contains calcium chloride as the main ingredient. It increases the concentration of dissolved calcium ions in the water, which helps maintain a balanced pH level and prevents damage to pool surfaces.

Factors to Consider

Before purchasing a pool calcium hardness increaser, there are several factors you should consider.

Pool Size

The size of your pool determines how much calcium hardness increaser you will need. You can calculate the volume of your pool by multiplying its length, width, average depth, and then multiplying that number by 7.48 (the number of gallons in one cubic foot). This will give you an estimate of how many pounds of calcium hardness increaser you need.

Calcium Hardness Level

It’s essential to know your current calcium hardness level before adding any chemicals to your pool. You can use a test kit or take a sample of your pool water to a local pool supply store for testing. Knowing your current levels will help you determine how much increaser you need to add.

Type of Pool

The type of pool you have also plays a role in choosing the right calcium hardness increaser. For example, if you have a vinyl-lined or fiberglass pool, you should opt for a non-granular formula to prevent staining or bleaching on these surfaces.

Product Reviews

After considering the above factors, it’s time to choose an actual product that fits your needs and budget. Here are some top-rated options based on my personal experience and research:

In The Swim Granular Calcium Hardness Increaser: This product comes in granular form and dissolves quickly without leaving any residue behind.
Liquid Calcium Hardness Increaser: This liquid formula is perfect for vinyl-lined or fiberglass pools as it won’t cause any staining or bleaching.
Kem-Tek Calcium Hardness Increaser: This product contains 100% pure calcium chloride for fast results without affecting pH levels.

Application Process

Once you have chosen your desired product, follow these simple steps for proper application:

1) Start by pre-dissolving the required amount of increaser in a large bucket filled with warm water.
2) Slowly pour the solution around the edges of your pool while circulating it with your pump.
3) Let it circulate for at least 24 hours before retesting your water levels.
4) Repeat if necessary until desired levels are reached.

In Conclusion

In conclusion, maintaining proper water chemistry is crucial for keeping your swimming pool clean and safe for use. A good quality calcium hardness increaser is an essential tool for achieving this balance. By considering factors like pool size, current levels, type of pool, and reading product reviews before purchase, you can ensure that you choose the right product that meets all your needs effectively. Remember always to follow proper application techniques for best results!
