Why Best Calcium Hardness Increaser is Necessary

As a pool owner, I have learned the hard way that maintaining proper calcium hardness levels in my pool is crucial for its overall health and longevity. That’s why I always make sure to use the best calcium hardness increaser available.

First and foremost, an adequate level of calcium hardness is essential for swimmer comfort. If the levels are too low, the water can become corrosive and cause skin irritation.

In addition to protecting equipment, the best calcium hardness increaser also helps maintain water clarity. When the calcium levels are balanced, it prevents scaling on pool surfaces and keeps the water from becoming cloudy. This not only makes my pool look more inviting but also reduces

My Buying Guide on ‘Best Calcium Hardness Increaser’

As a pool owner, maintaining the proper calcium hardness level in your pool is crucial for the health and longevity of your pool. Low calcium hardness can lead to corrosion of pool equipment and surfaces, while high levels can cause cloudy water and scaling. That’s where a calcium hardness increaser comes in. In this buying guide, I will share my personal experience and knowledge on finding the best calcium hardness increaser for your pool.

Understanding Calcium Hardness

Before diving into the buying guide, it’s important to understand what calcium hardness is and why it matters for your pool. Calcium hardness refers to the amount of dissolved calcium in your pool water. The ideal range for residential pools is between 200-400 parts per million (ppm). This helps maintain a balanced pH level and prevents damage to your pool.

Types of Calcium Hardness Increasers

There are two main types of calcium hardness increasers: calcium chloride and sodium carbonate. Calcium chloride is the most common type and typically comes in a granular form, while sodium carbonate is usually in a powder form. Both work effectively to raise calcium hardness levels, but there are some differences to consider.

Calcium chloride tends to dissolve faster and has a higher concentration of calcium per pound compared to sodium carbonate. However, it also tends to increase the pH level of your pool water more than sodium carbonate. On the other hand, sodium carbonate has less impact on pH levels but may take longer to dissolve.

Factors to Consider

When choosing the best calcium hardness increaser for your pool, there are a few factors you should consider:

1. Calcium Hardness Level: The first step is knowing your current calcium hardness level so you can choose an appropriate product that will raise it within the ideal range.

2. Pool Size: The size of your pool will determine how much calcium hardness increaser you need. Make sure to check the product label for dosing instructions based on your pool’s size.

3. Type of Pool: Some calcium hardness increasers are specifically designed for certain types of pools, such as vinyl or plaster. Be sure to read the product label to ensure it is suitable for your pool type.

4. Easy to Use: Look for a product that is easy to use and does not require any special equipment or tools.

5. Brand Reputation: It’s always a good idea to choose a reputable brand that has positive reviews from other pool owners.

My Top Picks

Based on my personal experience and research, here are my top picks for the best calcium hardness increasers:

1. Clorox Pool&Spa Calcium Hardness Increaser: This calcium chloride-based product is affordable and dissolves quickly, making it a popular choice among pool owners.

2. Robelle Calcium Plus: This sodium carbonate-based product is effective in raising calcium hardness levels without significantly affecting pH levels.

3. DryTec Calcium Hardness Increaser: This granular calcium chloride-based product is a bit pricier but has received high ratings for its effectiveness and ease of use.

Conclusion

Maintaining proper calcium hardness levels in your pool is essential for its health and longevity. By understanding the different types of calcium hardness increasers and considering factors such as your pool size and type, you can make an informed decision on which product will work best for your pool. Whether you choose Clorox, Robelle, or DryTec, any of these top picks will help keep your pool water balanced and clear all season long.
