Nicola Fraser –
Used FritzZyme 9 in a new saltwater tank with no fish initially. After adding the bacteria, I was able to introduce my fish within 3 days. Ammonia levels stayed stable and the tank settled quickly. Highly recommended for beginners.
Amy Paige –
The bacteria worked well in my 55-gallon reef tank. I added it during a water change and noticed a drop in nitrite levels within a week. It helped me avoid a long cycling period.
Alison Slater –
After setting up a new tank, I used FritzZyme 9 to jumpstart the biological filter. My fish were added immediately, and the water parameters remained stable. No fish deaths or stress observed.
