A great way to test the strength of your bleach solution

I regularly make my own chlorine bleach. Sodium hypochlorite (household liquid bleach) degrades over time and has a shelf life of about 3-5 months. Rather than stock up on bleach only to have it deteriorate over time, I buy pool shock (calcium hypochlorite) and use it to mix up a fresh batch of bleach as needed. I not only have the ability to store extra bleach without having to worry about the shelf life, but I also save a lot of money - a 1 lb package of pool shock is about $4, which can make A LOT of gallons of bleach. I wanted to test the strength of my bleach after it was diluted in a gallon of water to make sure the concentration was correct. I suspected that the most recent gallon I made was not strong enough, and I used these test strips to confirm my suspicion. After adding a bit more calcium hypochlorite to the solution, I was able to get the concentration correct; the test strips were noticeably darker and easy to read. (Just to be clear, I was testing the gallon of water that I'd added bleach to, not the bleach directly). Keep in mind that these test strips are not designed to test chlorine levels in tap water; if that's your purpose, then you need to buy a different product; this type of test strip is designed to measure levels of chorine in different dilutions (added to water) so that you know there is enough to sanitize or disinfect surfaces. For most microorgansims (bacteria and viruses), a level of 200 ppm is considered adequate. For killing mold, a higher concentration is necessary (I believe 2,000 ppm). The CDC has a really helpful list of how many ppm of bleach is required to kill various pathogens. I am very pleased with these test strips; they were easy to use and allowed me to verify the strength of my solution. I also found that I was able to rip a test strip in half so that I can make them last even longer. If you have any questions, I'm happy to try to help. Please consider leaving me feedback below if you found this review helpful.

I see several reviews stating that they are using these test strips on plain water and seeing no effect. Tap water or filtered water won't have any effect on these strips since the amount of chlorine in plain water is just too little. The minimum concentration of chlorine that would be visible with these strips is probably about 5ppm and even then it would be a very very light shade of purple. The main description photos show the different shades of purple for the concentrations of 10ppm, 50ppm, 100ppm, and 200ppm. Anything under 10ppm or over 200ppm would require a different type of test strip. I've been using these test strips in my business for over a decade to measure my chlorine concentration of sanitizing solution and they work very well. The health department usually stops by a few times a year and they've never had any issues with us using these test strips. The only issue I have with them is that some of the strips stick together and you might accidentally get 2 strips when you only need 1.

Will do the job but light on color compared to others.

Somewhat cheap. Color gray can be on the light side compared to others.

Used by thousands of restaurants.

These are what thousands of restaurants use to test for chlorine in sanitizer buckets and dish machines. I only wish they made a version with more detailed accuracy.

Not worth buying

I would never buy this again. More then 50% of the strips didn’t even work. It’s looks like they scammer but putting strips that don’t even work and I use them every day at least three or more time a day.

This works

Simple and classic but still the best solution. The plastic case is also good to avoid moisture

Total waste of money!

A total waste of a 20$ bill, may as well cut off a small strip of paper from a normal sheet of paper and see what test results your about to get. Save your money and do not buy this!

works well

It works ok but give 4 stars because Hydrion Chlorine Test Roll is cheaper and working better.
