The information on this product is vague. Whether or not the bacteria are even aquatic is questionable, especially because you apparently have to keep adding it, as if the bacteria cannot properly colonize in an aquarium. It is much safer to establish your biological filter without the use of additives. I only suggest you try products such as these in the case of an emergency.

I was having some trouble in cycling my tank, I added this stuff and almost right away my tank was crystal clear and the water was safe to add more fish.
