## Questions & Answers

**Q: Can we add this to an existing reef with slightly elevated ammonia?**
A: If by existing you mean live stock in it? Yes, and if you mean no stock but ammonia, yes again.  You might be better off doing a water change if you have life in tank though. If you dose this you will have to monitor nitrite and nitrate cycles.

**Q: Im new...will this kill off my invert food sources or hurt them in any way?**
A: It will not kill your invert food source. It’s bacteria that’s beneficial to your aquarium

**Q: Noob question how much of this do I use on a 32 gallon biocube? It’s a new tank I can’t find any measuring cups for ML anywhere n my town**
A: Once your tank has been fed regularly for a few days either with out without fish to start the bacterial cycle, add half during the first week and the other half during the 2nd.

Add a small amount after water changes is also a good idea for upkeep. Buy 2 bottles.

**Q: how long did it take for this product to bring down nitrite levels?**
A: I wouldn't use this product as a means of nitrite reduction. Live rock will do a much better job of that. I use this product as a means of adding biodiversity to my tank. It did nothing for nitrate levels.
