This article serves to inform potential owners that hot tub water care doesn’t have to be a daunting task, and that with a little bit of research, you can find the perfect brand to make your hot tub water care infinitely simpler. Keep reading to gain an overview of hot tub water care, and then take a closer look at the solutions offered by Sundance® Spas and others. 

Why Does Hot Tub Water Care Matter?

Hot tubs require significant water maintenance because of their continuous usage and complex nature. Their water is constantly circulated through a network of filters, jets, and heaters, making it difficult to maintain consistent water chemistry and cleanliness. Consistent utilization also increases the risk of bacteria, algae, and other contaminants in spa water. Keeping your hot tub’s water balanced and sanitary is the most effective and efficient way of maintaining safe, hygienic, and clear water in your spa.

Water Care Basics

Understanding the fundamentals of hot tub water chemistry is key to effective maintenance. Here are some crucial factors to monitor within your tub:

  • pH Levels: Ideally, your hot tub water should have a pH between 7.2 and 7.8. If the pH is too low, it can cause skin and eye irritation. If it's too high, it can lead to cloudy water and scaling.
  • Alkalinity: This chemical compound helps stabilize pH levels, preventing sudden fluctuations. Aim to keep alkalinity levels between 80-120 ppm.
  • Calcium Hardness: This refers to the concentration of calcium ions (Ca2+) in your water. Maintain calcium levels of 150-250 ppm to prevent scale buildup and corrosion of spa equipment.
  • Sanitizer Levels: Ensure the correct amount of chlorine, bromine, or alternative sanitizers are present to keep your water safe and clean.

Comparing Traditional and Advanced Water Care Systems

Traditional chlorine and bromine systems have been the standard for years, but advanced systems like oxygen, UV-C, and automated solutions can offer lower maintenance and a more natural water experience. Brands like Sundance® Spas now offer smartphone integrations that allow you to stay continuously updated on your hot tub water health and maintenance tasks, even automating some of the most demanding water upkeep duties. But we’ll get into that more later.

Traditional Systems vs. Advanced Systems:

  • Cost: Traditional systems are typically more affordable initially, but advanced systems may save money on chemical costs over time.
  • Maintenance: Traditional systems require frequent testing and chemical adjustments, while advanced systems automate much of the sanitization process.
  • Water Feel: Oxygen and mineral-based systems provide softer, less irritating water compared to standard chlorine or bromine treatments.
  • Environmental Impact: Oxygen and automated systems reduce reliance on chemicals, making them a more eco-friendly option.
  • Ease of Use: Traditional systems typically require manual testing, repetitive upkeep, and continuous purchasing of chemicals. Automated or modernized systems complete many of these tasks for you, keeping owners updated directly from their smartphones.

The Benefits of Effective Hot Tub Water Care

Let’s take a closer look at exactly why we want to maintain clean and healthy water in our spas:

  1. Comfort: Balanced water looks and feels good. Unbalanced water can irritate the skin, cause unpleasant odors, and hurt your eyes.
  2. Extended Lifespan: Properly maintained water will keep your spa’s parts in better shape, reducing damage to components, like the heater, jets, and water pump, from water that is too acidic or alkaline.
  3. Safety: By balancing your hot tub’s water, you eliminate harmful bacteria and pathogens. Bathing in unsanitary water can put your health at risk, exposing your body to germs and other irritants.
  4. Cost Efficiency: The healthier your water, the safer your investment will be. Regular chemical testing and water care will minimize the need for repairs and save you money on excess chemicals over time.
