If the calcium levels in your swim spa or hot tub water are too low, adding a little bit of “Hardness Increaser” can help bring them back up safely without making the water cloudy. When the calcium levels are right, your hot tub, swim spa, or pool will last longer, and the water will be less harsh on your skin and equipment.

We have SpaPure Hardness Increaser in our stock, available at an affordable price. To use it, just add one ounce of Hardness Increaser for every 500 gallons of water in your hot tub or swim spa while the water is circulating. You can find SpaPure Hardness Increaser at Aqua Living Stores, so give it a try and keep your hydrotherapy sessions healthy and happy!
