As someone who has owned a pool for several years, I have learned the importance of maintaining proper calcium hardness levels in my pool water. Calcium hardness refers to the amount of dissolved calcium in the water, and it is a crucial aspect of pool maintenance that is often overlooked.

First and foremost, having the right calcium hardness level ensures the longevity of your pool equipment. If the calcium levels are too low, it can lead to corrosion and damage to your pool’s pumps, filters, and other equipment. On the other hand, high calcium levels can cause scaling and buildup in your equipment, leading to reduced efficiency and costly repairs.

Furthermore, maintaining proper calcium hardness levels is essential for the safety and comfort of swimmers. Low calcium levels can cause irritation to swimmers’ skin and eyes, while high levels can make the water cloudy and unappealing. It is also worth noting that balanced calcium levels help maintain the pH balance of your pool water, making it easier to keep clean.

Using a high-quality calcium hardness increaser is crucial for achieving and maintaining optimal levels in your pool. These products are specifically designed to increase calcium levels without affecting other chemical balances in the water. They are also easy to use and can save you time and money in the long run by preventing damage to your

My Buying Guide on ‘Best Calcium Hardness Increaser’

Hi there, I’m glad you’re looking for the best calcium hardness increaser for your pool or spa. As a pool owner myself, I understand the importance of maintaining proper calcium hardness levels to keep the water balanced and healthy. After trying out different products, I have compiled a list of factors that you should consider when choosing the best calcium hardness increaser.

1. Calcium Hardness Levels

The first thing to consider is the current calcium hardness level of your pool or spa water. This can be easily determined by using a test kit or strips. The ideal range for calcium hardness is between 200-400 parts per million (ppm) for a pool and 150-250 ppm for a spa. If your levels are below this range, you will need a calcium hardness increaser to raise it.

2. Type of Calcium Hardness Increaser

There are two types of calcium hardness increasers available – liquid and granular. Liquid increasers are easier to use as they can be poured directly into the water without pre-dissolving. However, they tend to be more expensive than granular increasers. On the other hand, granular increasers require pre-dissolving in a bucket of water before adding it to the pool or spa.

3. Ingredients

When buying any pool product, it’s important to check the ingredients list to ensure it is safe for use in your pool or spa. The best calcium hardness increasers should contain only pure calcium chloride without any fillers or additives that can affect the water chemistry.

4. Brand Reputation

I always prefer buying products from reputable brands with good customer reviews and ratings. This ensures that I am getting a quality product that has been tried and tested by other pool owners.

5. Price

The price of calcium hardness increasers can vary depending on the brand and type of product. While it’s important not to compromise on quality, it’s also necessary to consider your budget when making a purchase.

6. Ease of Use

If you’re new to maintaining your pool or spa, you may want to opt for an easy-to-use calcium hardness increaser that comes with clear instructions on how much product to add per gallons of water.

7.Regular Testing and Treatment

In order to maintain proper calcium hardness levels, it’s important to regularly test your water and treat accordingly if needed. It’s recommended to test your water at least once a week and adjust accordingly using the recommended amount of calcium hardness increaser based on your current levels.

In conclusion,

The best calcium hardness increaser for you will depend on factors such as current levels, type of product, ingredients, brand reputation, price, ease of use, and regular maintenance needs. By considering these factors, you can make an informed decision and choose the best product for your specific needs.

I hope this guide has been helpful in your search for the best calcium hardness improver for your pool or spa!
