## Questions & Answers

**Q: is this product interchangeable with Hach 2105569?**
A: I don't believe so. The Hach 2105569 takes a 10ml sample and is best used in a Hach machine. The Barnant 1407799 takes a 5ml sample and is used in the Hach visual measurement kit. I use a Hach visual kit with the Barnant 1407799.

**Q: why are they saying, cannot be shipped to my address?**
A: It may be considered haz mat ?

**Q: Can these reagent pillows be used in another colorinator that is not the Hach brand? I have a Hanna free-chlorine chlorinator coming.**
A: It could be considered but we cannot confirm they will give the correct result.  If you want to try it, it would be best to do so with a known solution of chlorine or side by side comparing results to the proper manufacturers reagent.

**Q: what is the difference between "free" and "total" chlorine?**
A: Free chlorine is the amount of non-reacted available chlorine in a system. 
Total Chlorine is the amount of compost chlorine in a system including free chlorine, and reacted chlorine like chloramines.
