I don’t know how well this stuff works. All I know is I add it after any filter maintenance and whenever adding livestock and I’ve had no issues.
Great product arrived promptly.
This is an excellent product whenever I change the water or add water I pour some in
I have used this product on my tanks, and it helped my aquarium cycle very quickly, I used it at the end of last week and my aquarium is really looking great, and the fish are doing good now. I started my tank about 3 or 4 weeks ago, and used some other products, but was having problems with it cycling, after using Fritz Zymm 7 it seems to straightened out the problems I had. Very happy with the product, only if Hong I did not like was that you had to use a lot of the product.
This seems to do the job. I have not lost any fish or plants.
