Question:What makes this product refresh water only ?

Answer:  1. Nitrifying bacteria – These bacteria eat ammonia and nitrites. They require oxygen in the water to live. Nitrifying bacteria live on the surface of objects in your aquarium. 2. Denitrifying bacteria – These bacteria eat nitrates. They will only survive if no oxygen is present. Denitrifying bacteria live inside rock, ceramic and other porous materials where no air is present.

Question:Will these work for both freshwater and saltwater?

Answer:  It can only work for freshwater aquarium. Put it into saltwater aquarium will increase the level of nitrite. So, we do not suggest to use it in saltwater. Thanks.
