Expert Tips for Crystal Clear Hot Tub Water
Hot Tub Cleaning Guide Basics: Why It Matters
Understanding the risks of dirty hot tubs
- Legionella pneumophila: Causes Legionnaires’ disease, a potentially deadly lung infection that’s extra dangerous for folks over 50. The scariest part? You can catch this just by breathing in contaminated water vapor—you don’t even need to dip a toe in!
- Pseudomonas aeruginosa: Creates “hot tub folliculitis,” those red, itchy bumps and sometimes pus-filled blisters where your swimsuit covers. Not exactly the souvenir you want from your soak!
- Cryptosporidium: This sneaky parasite causes severe diarrhea after swallowing even tiny amounts of contaminated water. Fun fact: it’s super resistant to chlorine!
- E. coli, Staphylococcus, and Norovirus: These troublemakers cause everything from tummy troubles to painful UTIs.
Do’s and Don’ts for Hot Tub Health Safety:
Do’s
- Check disinfectant levels before each use
- Shower before and after hot tub use
- Maintain water temperature below 104°F (40°C)
- Sit upright to keep face above water
- Look for crystal clear water
Don’ts
- Enter with open cuts or wounds
- Use if you’ve had diarrhea in the past 5 days
- Swallow hot tub water
- Use a hot tub with sticky or slippery tiles
- Enter a strong-smelling hot tub

Recommended hot tub cleaning chemicals
Sanitizers
- Chlorine (1-3 ppm) – Quick-acting, budget-friendly, and gets the job done
- Bromine (3-5 ppm) – Less smelly, gentler on skin, and handles hot water like a champ
- Mineral sanitizers – Team up with chlorine/bromine so you can use less harsh chemicals
Water balancers
- pH increasers and decreasers (aim for 7.2-7.8 pH)
- Alkalinity adjusters (shoot for 80-120 ppm)
- Calcium hardness treatments (sweet spot: 175-250 ppm)
- Filter cleaners (both spray-on and soak types)
- Shell cleaners made just for spa surfaces
- Line flush products for pipes (never swap in vinegar here!)
- Anti-foam agents when bubbles go wild (and not in a good way)
Do’s and Don’ts when choosing cleaning products
Do’s
- Use products specifically made for hot tubs
- Follow those instructions to the letter
- Test water before and after adding chemicals
- Keep jets running when adding chemicals
- Leave the cover off for 15 minutes after adding chemicals
Don’ts
- Use household cleaners like bleach, ammonia or dish soap
- Mix different sanitizers (especially chlorine and bromine)
- Add chemicals while people are splashing around
- Toss chemicals into the wind or from up high
- Use harsh acids that can damage your equipment
Step-by-Step: How to Clean a Hot Tub Properly
1. Turn off power and drain
- The slow-and-steady route: Hook up a garden hose to your built-in drain valve and point it somewhere appropriate
- The speedy solution: Use a submersible pump (fancy name for a sump pump) and finish in 10 minutes instead of an hour!
2. Flush the lines
before
- Pop out those filter cartridges
- Add line flush product (follow the bottle’s instructions)
- Crank those jets to high for 15-20 minutes (leave the cover off!)
- Is it foaming like crazy? That’s normal! Just temporarily kill the jets or skim off the excess
3. Clean the shell and jets
- Spray everything with diluted white vinegar or a hot tub-specific cleaner
- Wipe with a soft cloth (scratching that acrylic is a no-no!)
- Give extra love to corners and jet areas where the funky stuff likes to hide
- Stubborn stains? Grab a non-scratch nylon scrubber
- Rinse super thoroughly (unless you want a bubble party when you refill)
4. Clean and replace filters
- Blast filters with your garden hose to knock out the chunky debris
- For a deeper clean, soak them in filter cleaning solution (overnight is best!)
- Rinse like crazy before putting them back (leftover cleaner = foam festival)
- Check for damage—if they’re looking sad or older than your favorite t-shirt (1 year+), time for new ones!
5. Refill and balance water chemistry
- Double-check all drain valves are closed tight
- Fill through the filter housing (prevents annoying air bubbles in your plumbing)
- Fill to the right level—usually halfway up the skimmer
- Power back on!
- Time for chemistry class! Test and balance in this order:
- Total alkalinity first (aim for 80-120 ppm)
- Then pH level (7.2-7.8 is the sweet spot)
- Finally, add your sanitizer (chlorine or bromine)
- Let those jets run on low for at least 20 minutes to mix everything nicely

Advanced Hot Tub Maintenance Tips for Crystal Clear Water
Weekly, monthly, and quarterly maintenance checklist
Weekly Must-Dos:
- Check those chemistry levels 2-3 times (pH, alkalinity, sanitizer)
- Give your water a good shock treatment (think of it as a water energy drink!)
- Wipe away any sneaky scum lines forming at the waterline
- Spray down those filters with your garden hose (they’ll thank you!)
Monthly Magic:
- Treat your filters to a spa day with a deep soak in cleaner
- Play “jet detective” – make sure each one is bubbling properly
- Let a pro check your water chemistry (sometimes our test strips need backup)
- Show your cover some love with a good clean and conditioning
Quarterly Quick-Fixes:
- Empty everything out for a fresh start
- Flush those pipes clean (they hide all sorts of gunk!)
- Give the shell a thorough scrub-down from top to bottom
- Check your cabinet for any weather damage or wear
How to shock your hot tub properly
- Check that pH level first (aim for 7.4-7.6) before adding anything
- Add shock when the sun goes down (UV rays are shock’s enemy!)
- Pop the cover off for at least 20 minutes afterward (let those chemicals breathe!)
- Make shocking a weekly habit, but do it more often if you’ve had a hot tub party
Signs your hot tub needs deep cleaning
- Water looking foggy or off-color even after you’ve added chemicals
- Funky smells that make your nose wrinkle (that’s bacteria throwing a party)
- Foam or scum that just won’t quit, no matter what you try
- Stubborn waterline rings or water that’s suddenly cooler than usual
- Slimy green or brown spots starting to form (yuck!)
