Frequently Asked Questions

Can I just put chlorine tablets in my hot tub?

Chlorine tablets are a convenient and cost-effective way to sanitize hot tubs, however, don’t just toss them in. Tablets (whether chlorine or bromine) are designed to go in a floater. That way they will dissolve slowly into the hot tub water over a period of several days.

How many chlorine tablets should I add to a hot tub?

For a hot tub, begin with 3-5 chlorine tablets every week for every 500 gallons of water. You might need to tweak this based on the tub’s size and other considerations.

Test the water regularly to ensure adequate chlorine levels.

What type of chlorine should I use in my hot tub?

For shocking your hot tub, we recommend using Sodium Dichlor Granular Chlorine like this one on Amazon. That’s the shock I use.

Granular spa shock is a great choice for sanitizing your hot tub because it’s easy to dose and won’t damage the acrylic shell. It’s also a cost-effective solution that will keep your hot.

For the sanitizing tablets themselves, I like these 1-inch chlorine tablets from Clorox on Amazon.

How to shock a hot tub with chlorine granules?

Add powdered chlorine shock near the water inlets and use the shock dose recommendations to determine how much you need. When adding, ensure the pump is running and the pH level is balanced for optimal effectiveness.

After adding shock, many experts recommend waiting 24 hours before using. But ultimately it comes down to the chlorine levels in the water.

So always test the water with a test strip before getting in.

How often should I test my hot tub’s chlorine levels?

It is important to test your hot tub’s chlorine levels at least once a week to ensure water quality and safety. But I actually like to test mine every time I get out after using it. That way, if I need to make any adjustments, it will be ready for me next time.
