Balanced calcium hardness for spa water

Maintaining the right calcium hardness is essential for long‑lasting spa surfaces and steady equipment performance. When hardness is too low, surfaces can become vulnerable and equipment may wear more quickly. A common, practical range to aim for is 200–400 ppm, which helps create a stable, comfortable water environment.

About SpaChoice 1-Quart Liquid Calcium Hardness Increaser

This liquid formula is designed for simple, accurate dosing and faster integration into spa water. Many users prefer the liquid option for its pour‑and‑go convenience, especially during routine balancing where precise adjustments matter.

  • The ideal hardness level is 200–400 ppm
  • 1 ounce of product per 500 gallons increases hardness by about 10 ppm
  • Customers prefer this liquid product as it can be easier to use than granular alternatives

How to use SpaChoice

  • Test the water with a calcium hardness test kit to determine the needed amount
  • With the spa on, pour the proper amount into the water
  • Run the filter for 1–2 hours to blend the calcium into the water
  • Retest in about 20 minutes and adjust as needed

What to expect after dosing

Following dosing, the water may feel more balanced and stable as calcium helps support surfaces and clarity. Regular testing helps you maintain the desired range for your spa experience, without guesswork.
