The Importance of Using the Best Calcium Hardness Increaser

As a pool owner, I have learned the hard way about the importance of maintaining proper calcium hardness levels in my pool water. When I first started maintaining my pool, I didn’t think much about calcium hardness and didn’t see the need for a calcium hardness increaser. However, after experiencing numerous problems with my pool, I quickly realized the necessity of using the best calcium hardness increaser.

First and foremost, having the correct level of calcium hardness in your pool water is essential for keeping your pool equipment and surfaces in good condition. If the water is too soft, it can cause corrosion and damage to your pool’s metal components such as pumps and filters. On the other hand, if the water is too hard, it can lead to scaling on your pool walls and equipment, which not only looks unsightly but also reduces their lifespan.

Moreover, maintaining proper calcium hardness levels also ensures that your pool water is safe for swimming. Low levels of calcium can cause the water to become aggressive and corrode metal surfaces. On the other hand, high levels of calcium can make it difficult for chemicals to work effectively, leading to cloudy or discolored water. By using a good quality calcium hardness incre

My Buying Guide on ‘Best Calcium Hardness Increaser’

As a pool owner, maintaining the right balance of chemicals in your pool is crucial for its overall health and longevity. One of the most important aspects of pool maintenance is keeping the calcium hardness levels in check. If your pool’s calcium hardness is too low, it can cause damage to the pool’s surface and equipment. On the other hand, if it’s too high, it can lead to cloudy water and scale buildup. That’s where a calcium hardness increaser comes in handy. In this buying guide, I will share my personal experience and tips on choosing the best calcium hardness increaser for your pool.

Understanding Calcium Hardness

Before diving into the details of buying a calcium hardness increaser, it’s essential to understand what it is and why it matters. Calcium hardness refers to the amount of dissolved calcium in your pool’s water. The ideal range for calcium hardness in a swimming pool is between 200-400 parts per million (ppm). Anything below or above this range can cause problems for your pool.

Things to Consider Before Buying

When shopping for a calcium hardness increaser, here are some factors that you should keep in mind:

1. Type of Calcium Hardness Increaser

There are two types of calcium hardness increasers available: granular and liquid. Granular increasers are easier to use as they dissolve quickly and don’t require pre-mixing with water. However, they may leave behind residue that can clog filters or cause cloudy water. On the other hand, liquid increasers are mess-free but may require more time to dissolve completely.

2. Calcium Chloride Content

Calcium chloride is the main ingredient in most calcium hardness increasers. It’s essential to check the percentage of calcium chloride in the product you are considering. A higher percentage means that the product will be more effective in increasing calcium hardness levels.

3. Brand Reputation

When it comes to pool chemicals, it’s always best to go for trusted and reputable brands. These brands have a proven track record of producing high-quality products that are safe and effective for your pool.

4. Pool Size

The size of your pool plays a significant role in determining the amount of calcium hardness increaser you’ll need. Make sure to calculate the volume of your pool accurately before purchasing to avoid under or over-dosing.

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 granular increaser is made with 100% pure calcium chloride and dissolves quickly without leaving any residue. It’s also budget-friendly and suitable for all pool types.

2. Leslie’s Calcium Hardness Increaser

This liquid increaser is highly concentrated, meaning a little goes a long way. It also contains a stabilizer to prevent calcium buildup on surfaces and equipment.

3. In The Swim Pool Calcium Hardness Increaser

This granular increaser has 95% pure calcium chloride content, making it highly effective in raising calcium hardness levels. It’s also fast-acting and dissolves easily without clogging filters.

Conclusion

Investing in a good quality calcium hardness increaser is essential for maintaining a healthy pool. Consider factors like type, brand reputation, and pool size before making a purchase decision. With my top picks and tips in mind, you can choose the best calcium hardness increaser for your pool and enjoy crystal clear water all season long.
