Why I Always Use Spa Calcium Hardness Increaser

As a frequent spa user, I have learned the importance of maintaining proper water balance in order to fully enjoy the benefits of soaking in a hot tub. One crucial factor that is often overlooked is the calcium hardness level of the water. This is where Spa Calcium Hardness Increaser comes in.

I have found that without this product, my spa water becomes cloudy and uninviting. This is because low calcium levels can cause corrosion to metal parts, such as the heater and pump, leading to expensive repairs. Additionally, low calcium levels can also damage the spa’s surface and cause skin irritation.

By using Spa Calcium Hardness Increaser, I am able to easily raise the calcium level in my spa to the recommended range of 150-250 ppm (parts per million). This not only protects my spa from potential damage but also ensures a comfortable and safe experience for me and my guests.

Furthermore, using this product has saved me time and money in the long run. I no longer have to constantly drain and refill my spa due to imbalanced water chemistry. Instead, I can simply add Spa Calcium Hardness Increaser as needed to maintain optimal levels.

My Buying Guide on ‘Spa Calcium Hardness Increaser’

In my experience as a spa owner, one of the most important factors to maintain is the calcium hardness level in the water. This not only affects the overall quality of the water, but also helps to protect and prolong the life of your spa equipment. After trying and testing various products, I have found that a spa calcium hardness increaser is an essential addition to my spa maintenance routine. In this buying guide, I will share with you my tips and recommendations for choosing the right spa calcium hardness increaser.

What is Spa Calcium Hardness Increaser?

Before we dive into the buying guide, it is important to understand what exactly a spa calcium hardness increaser is. Simply put, it is a chemical compound that raises the level of calcium in your spa water. The ideal range for calcium hardness in spas is between 150-250 ppm (parts per million). If this level falls below or above this range, it can lead to various issues such as corrosion, scaling, cloudy water and damage to equipment.

Factors to consider before buying a Spa Calcium Hardness Increaser

  • Spa Size: The size of your spa will determine how much calcium hardness increaser you need. It is important to measure your spa’s volume (in gallons) so you can purchase the right amount of product.
  • Calcium Hardness Level: Before adding any chemicals to your spa water, it is crucial to test its current levels. This will help you determine how much calcium hardness increaser you need and prevent over or under-dosing.
  • Type of Spa: Different types of spas may require different amounts or types of chemicals for maintenance. Make sure to check if the product you are considering is suitable for your specific type of spa.
  • User-Friendliness: Some calcium hardness increasers may require pre-dissolving before adding to the water while others can be directly poured into the water without any preparation. Choose a product that fits your convenience and comfort level.
  • Safety Measures: Always read and follow safety instructions on the product label carefully. Look out for any warnings or precautions and make sure to store and handle the product properly.

Recommended Products

  • Leisure Time Calcium Booster: This product has been my go-to choice for increasing calcium hardness in my spa. It dissolves quickly without any residue and helps prevent scale buildup on surfaces.
  • Natural Chemistry Pool Perfect Plus PHOSfree: If you prefer using natural products in your hot tub, then this could be an ideal choice for you. It increases both calcium and magnesium levels while also removing phosphates from the water.
  • InSPAration Liquid Calcium Balancer:This liquid formula makes dosing easy and precise without causing any cloudiness in the water. It also contains no harsh chemicals or dyes making it safe for both users and equipment.

Tips for using Spa Calcium Hardness Increaser

  • Dissolve the recommended amount of product in a bucket of warm water before adding it to your spa to avoid any undissolved particles settling on surfaces.
  • Add small amounts at a time until desired levels are reached rather than pouring all at once which could lead to overshooting recommended levels.
  • Maintain proper circulation after adding any chemicals into your hot tub by running jets or filtration system for at least 30 minutes.

I hope this buying guide has helped shed some light on what factors you should consider when purchasing a Spa Calcium Hardness Increaser. Remember, keeping proper levels of calcium hardness will ensure clear, balanced and safe water in your hot tub while also protecting its components from damage. Happy soaking!
