Question 1

How much chlorine should I use in my hot tub?

Accepted Answer

The ideal chlorine level for a hot tub is between 3-5 ppm (parts per million). To achieve this, it is recommended to add around 1 tablespoon of chlorine granules per 100 gallons of water.

Question 2

What type of chlorine is best for hot tubs?

Accepted Answer

Sodium dichlor is often considered the best type of chlorine for hot tubs. It dissolves quickly, is pH neutral, and is less harsh on the skin and eyes compared to other types of chlorine.

Question 3

How often should I add chlorine to my hot tub?

Accepted Answer

It is recommended to add chlorine to your hot tub after each use. Additionally, you should check the chlorine levels at least once a week and adjust as necessary to maintain the appropriate levels.

Question 4

Can I use chlorine tablets in my hot tub?

Accepted Answer

While chlorine tablets are commonly used in swimming pools, they are not ideal for hot tubs because they dissolve slowly and can lead to uneven chlorine distribution. Granules or liquid chlorine are generally more effective for hot tubs.

Question 5

Is chlorine safe for hot tub users?

Accepted Answer

When used correctly, chlorine is safe for hot tub users. It effectively kills bacteria and helps maintain clean water. However, excessive chlorine can cause skin and eye irritation, so it’s important to monitor and maintain the proper chlorine levels.
