Plastic refill bottle contains 32oz. 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!!"

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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Big money saving, time saving bottle! *by D***K on September 12, 2016* Love this big bottle of Blue Devil chlorine tester!
