Buying Guide for Hardness Increaser for Pools
Understanding Why Hardness Matters in My Pool
When I first started maintaining my pool, I learned that calcium hardness plays a crucial role in keeping the water balanced. If the hardness is too low, the water can become corrosive and damage the pool surfaces and equipment. On the other hand, too much hardness can cause scaling. So, using a hardness increaser helps me keep the calcium levels in the ideal range to protect my pool.
Identifying the Right Type of Hardness Increaser
I found that most hardness increasers contain calcium chloride as the active ingredient. It dissolves quickly and effectively raises the calcium hardness level. When choosing a product, I made sure it was suitable for my pool type, whether it’s vinyl, fiberglass, or concrete, since some products are formulated with these specifics in mind.
Checking the Calcium Hardness Level Before Buying
Before purchasing a hardness increaser, I always test my pool water’s calcium hardness using a reliable test kit. This step is essential because I only add the product if the levels are below the recommended range, typically between 200 and 400 ppm. This way, I avoid overcorrecting and creating other water balance issues.
Considering Pool Size and Dosage Requirements
One important factor I consider is the size of my pool. The amount of hardness increaser needed depends on the volume of water. Most products provide dosage instructions based on pool size and desired increase in ppm. Knowing my pool’s exact volume helps me add the correct amount, preventing waste and ensuring effective treatment.
Ease of Application and Safety Precautions
I prefer hardness increasers that are easy to apply, usually in granular form that dissolves quickly. When using these chemicals, I always follow safety guidelines: wearing gloves, avoiding inhalation of dust, and adding the product gradually to the pool water to prevent cloudiness or other issues.
Storage and Shelf Life Considerations
Since I don’t add hardness increaser frequently, I look for products with a good shelf life and store them in a cool, dry place away from moisture. Proper storage ensures the product remains effective whenever I need to use it.
Final Thoughts Based on My Experience
Using a hardness increaser has made maintaining my pool’s water chemistry much easier. By regularly testing and adjusting calcium hardness, I prevent damage and extend the life of my pool surfaces and equipment. When buying, I focus on the product’s suitability for my pool type, clear dosage instructions, and ease of use to achieve the best results.
