Review: Great Big money saving, time saving bottle! - Love this big bottle of Blue Devil chlorine tester! It is so much cheaper than buying it in that tiny winey little bottle that I have to keep on purchasing!I use it to test the chlorine levels in my pool as well as my hot tub. It saves me time and money which is what I always look for! The only issue I had in the beginning was trying to find a dropper but my husband gave me an empty bottle of his nasal spray and it works like a charm!
Review: Price is Right, Great Chlorine Test Reagent... - This product is very good and accurate too! The price point is awesome and I can and will recommend this bulk product purchase. Dispensing from this larger jug to a smaller test dispenser is a bit tricky but solved with a spice meat injector!! "Now Good To Go!!" R/ KMW

## Questions & Answers

**Q: how many fluid ounces  ?**
A: 32 fl. Oz.

**Q: Does this stuff good for checking bromine?**
A: I never had to test for bromine myself. I did learn that it can be used for bromine however you have to double the amount. So if your comparator says it's 1ppm of Cl2 then it's 2ppm bromine.

**Q: Can check chlorine on kitchen faucet or showers in house?**
A: It can be used to check the chlorine in any water. The question I would have is what is your acceptable limits and where to find a scale for your readings. Both of those I can not answer for you.

**Q: Does this have an expiration or best by date?**
A: no exp date
