Make Balancing Your Water Easier & More Cost-Effective with AquaDoc's Calcium Hardness Increaser

Ensure Proper Water Hardness Levels in Your Hot Tub

  • Improve Water Balance: AquaDoc's Calcium Booster quickly raises your spa water's hardness to the optimal level, maintaining a balanced water environment.
  • Cost-Effective Solution: Our professional-grade product helps avoid the frequent need for water testing and chemical adjustments, saving you money in the long run.

Avoid Corrosion, Etching, and Staining

  • Protect Your Spa Investment: Stay ahead of soft water issues with AquaDoc's Hot Tub Calcium Increaser. Guard against corrosion, etching, and unsightly stains that can damage your spa equipment and aesthetic appeal.
  • Maintain Calcium Levels: Our spa calcium booster helps prevent calcium levels from dropping too low, ensuring your hot tub or spa water remains balanced and protective.

How It Works

  • Effective Hardness Increase: AquaDoc's Hot Tub Calcium Hardness Increaser works efficiently to raise your water's hardness by 10 ppm or more per ounce, ensuring your spa water stays balanced.
  • Rapid Absorption: Our product easily absorbs into the water, providing a quick and effective solution to calcium hardness issues.

The Hardness Increaser Hot Tub Owners Love

  • Essential Spa Chemical: A calcium hardness increaser is a must-have for hot tub owners. Without proper calcium levels, your water balance can become unbalanced, leading to potential issues.
  • Always Prepared: Keep AquaDoc's Hot Tub Calcium Booster on hand to maintain your water's hardness levels, ensuring a consistently enjoyable and hygienic spa experience.

Easy to Use, Made in the USA

  1. Check Current Calcium Levels: Assess your water's current hardness level to determine the necessary adjustments.
  2. Administer the Increaser: Add 1 ounce of AquaDoc's Calcium Increaser to your spa water for every 10 ppm of hardness increase needed.
  3. Achieve Desired Hardness Level: Turn on your spa equipment and gradually add the recommended amount of increaser.
  4. Monitor and Adjust: Run the filter for 1-2 hours, wait 20 minutes, and then retest the water to ensure the hardness level is as desired.
