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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Does exactly as advertised *by M***S on 16 May 2025* As per advertised, this was used to bring down my phosphate, I under dosed as I didn't want to crash my levels and was very happy with the outcome ### ⭐ Review *by T***. on 24 June 2024* This product doesn’t work.
