## Questions & Answers

**Q: When adding this to your reef tank, is it supposed to look cloudy when adding to the water. It seemed to also have little particles floating around?**
A: Yes, this is normal. This is the Part 2 reagent reacting with the already existing chemicals in the water. Add gently and slowly to a high flow area of the tank and allow it to disperse in a wider area. If it lands on anything, it isn't harmful, just keep an eye on it as some things may be a bit more sensitive, however this is made for the reef and for adding directly to the reef so just take your time, add the two parts separately, and slowly :)
