How to counteract chlorine in a spa pool

Monday, July 13, 2020

If you own a spa pool, at some point you’ll find yourself facing high chlorine levels. Most of the time it’s not even intentional, it just happens. If you’ve recently found yourself in that situation, don’t worry! At mySpa Sydney we’ve got you sorted. Here are some tips on how to counteract too much chlorine in a spa pool.

What causes high chlorine levels?

High chlorine levels can be caused by things such as putting too many chlorine tablets in your pool. You may have put more tablets than your spa pool actually needs without realising it. Or you may have added a bit too much shock to the water. Having a spa pool with high chlorine levels can happen to anyone.

How much chlorine should there be?

To check how much chlorine should be in your spa pool, make sure to test your pool water with either test strips or a liquid test kit. This will give you the most accurate result. An ideal chlorine level is 3 ppm. If you’re testing your spa pool several times a week, keep track of what your levels are and adjust accordingly if necessary. If your levels are below 2 ppm, it may be because your spa pool is not properly sanitized. This means it could be unhygienic and grow a lot of gross things in there. On the other hand, if the chlorine levels in your spa pool are above 4 ppm, you’ll need to bring those levels down to a safe range as soon as possible.

Effects of too much chlorine

If your spa pool has too much chlorine, you may notice things such as your swimwear fading in colour after one use. Too much chlorine may also start to damage your pool cover. Having too much chlorine in the spa pool can be dangerous if you have friends and family members who have sensitive skin or underlying health conditions. For example, it may cause eye irritation, over-dried skin, and possibly some breathing problems. If there’s too much chlorine it will vaporise and form gas that floats just above the surface of the water. If this vapor is inhaled it can inflame airways and exacerbate certain breathing conditions.
