Free chlorine reacts with ammonium ions and organic compounds to form chlorine compounds resulting in diminished disinfecting capabilities compared with free chlorine. These chlorine compounds together with chloramines form combined chlorine. Combined chlorine and excess free chlorine together result in total chlorine. While free chlorine has a much higher disinfectant potential, combined chlorine has a much higher stability and has a lesser volatility. There should be sufficient levels of unreacted free chlorine for adequate disinfection, but not so much as to become harmful.

If you want to:
- Make product changes;
- Create something not in stock
6,000 + (and growing) factories in our existing network are eager to make it for you.
When it comes to selling in stock products, we are no difference from many other Internet retailers, but we take pride in going extra miles to do something special for you: Have some products custom made for you.
We cannot do everything, but we usually can accommodate a certain changes in product options such as color, size, material, or minor design twist. We primarily work with vendors or factories, not individual artist or craftsman. For custom made products, we usually only cater to bulk size order that meets the minimum quantity requirement of a single factory run. Don't be shy. Ask. What we can accomplish may surprise you!
