## Questions & Answers

**Q: Should i use this product on a new tank with live sand and carib sea life rock?**
A: Yes, this product jumpstarts the system bio-load. With the live sand and the rock your system should be cycled in under a weeks time you'll need a source of ammonia as well.

**Q: The title is for "one & only" but the images show "waste away". which is correct?**
A: You have to select the one and only in the tab below then it will change to the correct one also pick the ounce size you want

**Q: is this a complete kit that comes with an ammonia source?**
A: This is only the bacteria.  Amazon does sell a kit with ammonia and bacteria for 18/19 bucks.

**Q: Is this product the same with One and Only bacteria? I'm buying One and Only so I'm not sure if I still need to get this one.**
A: never have used one and only .. but waste away worked great for me .
