Best Hot Tub Chemical Routine: Step-by-Step Guide for Crystal Clear Water

Maintaining crystal-clear water in your hot tub isn’t just about aesthetics—it’s essential for hygiene, safety, and ensuring your spa equipment lasts longer. A consistent and effective chemical routine will keep your hot tub water balanced and free from harmful bacteria. In this step-by-step guide, we'll show you the best hot tub chemical routine to follow so you can enjoy clean, clear water every time you soak.

1. Test Your Water Regularly

The foundation of any effective hot tub maintenance routine is regularly testing your water. It's crucial to check for the pH, alkalinity, and sanitizer levels to ensure everything is balanced.

• When to test: You should test your hot tub water at least 2-3 times a week, especially if the hot tub is used frequently.
• What to use: Use a reliable test kit or test strips to measure the chemical levels. Make adjustments based on the results to maintain the right balance.

2. Balance the pH and Alkalinity Levels

Maintaining the correct pH and alkalinity levels is essential for comfortable water and to prevent damage to your hot tub components. An unbalanced pH can cause eye and skin irritation or corrode your spa's equipment.

• Ideal levels: The pH should be between 7.2 and 7.8, and the alkalinity should be between 80 and 120 ppm.
• Adjusting levels: If the pH or alkalinity is too low, use a pH increaser like AquaDoc’s Hot Tub pH Up. If it’s too high, use a pH decreaser from our AquaDoc Hot Tub Care Collection.

3. Sanitize the Water

Sanitizing your hot tub is critical for eliminating bacteria and keeping the water safe for use. The two most common sanitizers are chlorine and bromine, with each having its pros and cons.

• Chlorine: A popular choice for hot tubs, chlorine is effective at killing bacteria quickly. Add AquaDoc Chlorine Granules directly to your water for fast and effective sanitization.
• Bromine: Bromine is a more stable sanitizer in higher temperatures, making it ideal for hot tubs. It’s less harsh on the skin and is available in tablets that dissolve slowly in the water.

4. Shock the Water Weekly

Even with proper sanitization, organic matter such as oils, lotions, and dirt can accumulate in the water. Shocking the water breaks down these contaminants and restores your sanitizer’s effectiveness.

• When to shock: Shock your hot tub once a week or after heavy use.
• What to use: Use AquaDoc Hot Tub Shock to oxidize the water and eliminate contaminants.

5. Add a Water Clarifier

If your hot tub water is starting to look cloudy, a water clarifier can help. Clarifiers work by binding small particles together so that your filter can easily remove them, leaving the water crystal clear.

• How to use: Add a dose of AquaDoc Water Clarifier after shocking the water, following the recommended guidelines on the product.

6. Use a Scale and Stain Preventer

Hard water can lead to scaling and staining in your hot tub, which can cause damage to the equipment over time. Using a scale and stain preventer helps keep your spa surfaces and pipes free from mineral buildup.

• Prevention: Add AquaDoc Scale and Stain Preventer to your weekly routine to keep your hot tub’s surfaces and pipes in good condition.

7. Clean and Replace Filters Regularly

Dirty filters can lead to poor water circulation, cloudy water, and strain on your hot tub’s pump. Cleaning or replacing your filters regularly ensures that your spa water stays clean and clear.

• How to clean: Remove the filters and rinse them thoroughly every two weeks. Deep clean them using a filter cleaner from our AquaDoc Hot Tub Care Collection monthly.
• When to replace: Filters should be replaced every 12-24 months, depending on use and condition.

Maintaining a Clean Hot Tub

Following these steps regularly will ensure that your hot tub stays in pristine condition, providing you with crystal-clear, relaxing water every time. Remember, maintaining your hot tub’s water quality is not just about comfort—it’s essential for the safety and longevity of your equipment. Keep your hot tub clean and balanced with products from the AquaDoc Hot Tub Care Collection, and enjoy worry-free soaks all year round.
