The 3 most common questions I get about using liquid bleach for my pool

Often times, when I meet with pool owners I get some head scratching.  They aren’t sure what to think when I tell them I mainly use liquid bleach or chlorine.

It doesn’t take long for them to head to the pool store and share with the employees what they have learned.  I did this too when I found out about using bleach and liquid chlorine.

Which the pool store unknowingly misinforms them even further.  It’s not that the pool store is bad or anything like that.  In their defense, they only know what they have been taught.  I have met some great pool store owners as well – some that tell customers upfront about issues with using pucks or powder.  Unfortunately the majority are not as honest or informed.

Here are the top 3 questions/comments I hear:

1 Won’t bleach or liquid chlorine bleach my liner?

2. Doesn’t the bleach irritate your skin and eyes?

3. The pool store guy told me that liquid chlorine or bleach isn’t as effective as tablets or powder shock.


  1. In regards to a bleached liner – 1st. Liquid chlorine and bleach are the same thing.  Bleach will not “bleach” your liner any more than liquid chlorine or tablets or powder shock.  In fact you are more likely to bleach your liner by dumping powder shock into your pool.  The granules can settle at the bottom of the pool and cause bleaching.  The UV from the sun in combination with chlorine in any form is also known to fade your liner.  No matter which method you use, your liner will fade over time. The quality of your liner can also play a role.  There are some pigments that are more likely to fade than others.  Our liner is going on 3 years and does not have any noticeable fading.  Regardless, here are some ways to properly add liquid chlorine to ensure it is not sitting on your liner.
  • Pour slowly
  • Pour in front of your return jet
  • Make sure pump is on
  • Use pool math to ensure you are adding the proper amount for your pool.  Dumping chemicals in here and there is not recommended.  Do yourself a favor and purchase the test kit.

2. Hair, Skin, Eyes – If you are testing daily and following our method, you will never have to worry about stinging eyes, irritated skin, or dry brittle hair.  In fact I am in our pool for hours at a time teaching swimming lessons.  I never have issues with irritation, and my students and or other swimming friends never complain.    Just make sure you test daily and keep everything within the recommended range.

3.  Chlorine effectiveness – This is one of most popular comments I receive.  Chlorine is chlorine.  Doesn’t matter if it’s in a tablet and powder or liquid bleach or liquid chlorine.  The difference is that the tablets contain CYA and the powder contains calcium.  Overtime tri-chlor or di-chlor tablets will cause CYA levels to raise to unmanageable levels, which WILL reduce the effectiveness of your chlorine and cal-hyp0 powder will cause hardness to rise causing scaling and other issues that you DON’T want to deal with.  By testing your water daily, you will know exactly how much chlorine you will need.  You will also know how much CYA you need, which you can add manually.  If you haven’t read my posts about all in one tabs – make sure you check it out!

In conclusion – liquid chlorine and or bleach is the best option to sanitize your pool.  You know exactly what is in it and you don’t have to worry about unmanageable levels of hardness or stabilizer from using powder shock(calcium hypo) or tablets (tri chlor)(di-chlor).  With liquid chlorine you know that it’s killing the nasty stuff and you also know it’s not adding other things to reduce its killing of the nasty stuffs potential!  You will save money overtime by knowing exactly how much you will need to keep your pool sanitized and sparkling all season!

Happy Saving, Happy Swimming, Happy Summer,
