Hot Tub Calcium Hardness Increaser

From the Brand Professional Grade, we aim to fix your water balance headaches by providing you with the spa chemicals you need to address your everyday hot tub maintenance issues. After struggling with our own pool and hot tub maintenance for years, we realized there was a shortage of quality chemicals on the market. Following rigorous testing, we launched our lineup of pro-grade chemicals to help solve your hot-tub related problems.

We love what we do because there's nothing better than seeing our community of happy hot tubbers enjoy their leisure time soaking in the tub. Hot tubs have the amazing ability to bring friends, family, and relationships together. And in our opinion, the best time to hot tub is on the weekend!

Moving on to our Customer Favorites, let's dive into the details of our Calcium Increaser Granules, a product designed to help balance the calcium hardness in your hot tub. To use AquaDoc's Calcium Increaser Granules, first check your water levels. The ideal calcium hardness level should be between 180-260ppm, or 40-80ppm if you have a saltwater spa system.

One ounce of our Calcium Increaser Granules will increase the hardness level of 500 gallons of water by 10ppm. After determining your desired hardness level, simply pour the product into your spa while the equipment is running. Run the filter for 1-2 hours, wait 20 minutes, and then retest the water. It's always better to start with a smaller dose and measure before adding more.

Our spa calcium booster, along with all other AquaDoc hot tub chemicals, are proudly made in the USA. By using our Calcium Increaser Granules, you can prevent scale formation, corrosion, and etching of surfaces, ensuring your hot tub water is properly balanced and your equipment is well-protected.

In addition to the Calcium Increaser Granules, we also offer an Alkalinity Booster and a Non-Chlorine Shock treatment, all of which are designed to make balancing your hot tub water easier and more cost-effective. Our products are backed by a 4.6, 4.8, and 4.5-star customer rating, respectively, so you can trust that you're getting high-quality spa chemicals that deliver results.
