Buying Guide for Pool Water Hardness Increaser

Understanding Water Hardness

When I first started managing my pool, I was surprised to learn about water hardness. Water hardness refers to the concentration of calcium and magnesium in the water. A balanced level of hardness is crucial for preventing corrosion of pool equipment and surfaces, as well as avoiding skin and eye irritation.

Why I Need a Hardness Increaser

I quickly realized that my pool’s hardness levels were too low, which led to issues like etching of plaster surfaces and discomfort while swimming. A hardness increaser helps to raise the calcium levels in the water, making it more comfortable and protecting my investment in the pool.

Identifying Hardness Levels

Before purchasing a hardness increaser, I learned to test my pool water regularly. I use test strips or a liquid test kit to measure the calcium hardness. The ideal range for most pools is between 200-400 ppm (parts per million). Knowing my pool’s current levels helps me determine how much increaser I need.

Types of Hardness Increasers

There are different types of hardness increasers available, primarily calcium chloride and calcium carbonate. I found that calcium chloride is a fast-acting option, while calcium carbonate releases calcium more slowly. Depending on my pool’s needs, I choose the type that best suits my situation.

Calculating the Right Amount

I learned that it’s important to know how much hardness increaser to add. The instructions usually provide guidelines based on the volume of my pool water. I make sure to calculate the amount accurately to avoid over-treating, which can lead to other issues.

How to Add the Increaser

Adding the hardness increaser is straightforward. I dissolve the required amount in a bucket of water before pouring it into the deep end of the pool. This helps to ensure even distribution. After adding, I run the pool pump for several hours to circulate the water properly.

Monitoring Water Balance

After I add the hardness increaser, I monitor my pool’s water chemistry closely. I check the calcium hardness levels again after 24 hours to see if they have reached the desired range. I also keep an eye on other chemical levels, like pH and alkalinity, as they can be affected.

Maintaining Optimal Hardness Levels

To maintain optimal hardness levels, I regularly check my pool water. I’ve found that factors like rainfall and water evaporation can affect hardness. I keep a log of my readings so I can track changes over time and adjust as necessary.

Safety Precautions

When handling any pool chemicals, including hardness increasers, I always wear protective gear like gloves and goggles. I also store the chemicals in a cool, dry place away from direct sunlight. Following safety guidelines helps me avoid accidents.

Managing my pool’s water hardness has become an essential part of my routine. With the right hardness increaser and a bit of knowledge, I can ensure my pool remains a safe and enjoyable place for my family and friends.
