Myths and misconceptions surround our everyday lives, and sometimes it’s hard to distinguish fact from fiction. Save yourself time and money by knowing common hot tub myths and the facts.
Myth #1: Use Household Bleach as a Sanitizer & Cover Cleaner.
Fact: People may say it’s ok to use household bleach as a hot tub or pool sanitizer. Here’s the thing though: household bleach damages the finish of your hot tub, deteriorates filter media and completely wrecks your hot tub cover, not to mention what it does to your heater and pump seals.
Tip: High chlorine or bromine levels can also trash the underside of your spa cover. Testing your sanitizer levels regularly and using a ThermoFloat blanket can prevent this problem. Oh, and leave your cover open for half an hour or so after adding any chemicals.
Bottom line: Do not use liquid bleach! Pick a sanitizing system designed for hot tubs.
Myth #2: Adding Antifreeze to Your Hot Tub is a Good Idea.
Fact: Antifreeze is extremely difficult to flush completely out of the system once it is added and residual antifreeze can be extremely toxic when absorbed through the skin.
If you must use antifreeze, use good quality RV antifreeze designed to keep potable water systems from freezing. You’ll still have to flush all that out when you reopen the spa, but you’ll have that added protection.

Myth #3: You Don’t Need Chemicals if You Have An Ozonator.
Fact: Ugh, I hear this all the time. The thing is, ozone has a very short half-life in water (about 15 minutes) so it’s not totally effective as a sanitizer. You’ll still need to use a system like bromine, Cleanwater Blue or Nature 2 to keep your hot tub healthy.
There’s good news though! Ozonators do decrease the amount of sanitizer needed (up to 25%) to achieve sanitized water.
Myth #4: Chlorine Causes my Eyes to Burn in The Hot Tub.
Fact: Maybe, but probably not. Chlorine can cause skin irritation, but the most common cause of burning eyes while soaking in a hot tub is imbalanced pH and/or Alkalinity. Low pH results in acidic water, while high alkalinity can make water caustic.
Prevent burning eyes by testing and balancing your water once a week.
Myth #5: Clean Your Filter by Running it Through a Dishwasher.
Fact: I cannot emphasize enough how much you should not do this. The high heat in your dishwasher is a super quick way to deteriorate the filtering media and ruin the cartridge.
Clean your filter properly by simply soaking it in a filter cleaning solution for 1-2 hours and rinsing it thoroughly. This will remove dirt and oil while maintaining the integrity of the filter media.
Filter extra grimy? That happens, so there are specialized filter cleaning tools like the Jet Stream Filter Cleaner System.
Myth #6: Use pool chlorine tabs in a hot tub.
Fact: Hold your horses there. These tablets are designed to dissolve slowly in cold pool water. Putting them in hot spa water will cause them to dissolve quickly and way, way over chlorinate the water.
Over chlorinated water is not only harmful to you, but your hot tub will pay the price as well. If you like tablets, do the smart thing and use bromine.
