Review on 🐠 ATM Aquarium Products: Freshwater Colony Nitrifying Bacteria for Effective Aquarium Maintenance by Randi Hernandez

I've tried quite a few bacteria in a bottle and had good results with Tetra Safe Start, but decided to give it a try. I used this in a 20 gallon fresh water tank that I was planning to install a new filter in and wanted to skip the mini cycle that usually follows a filter change. I followed the directions on the bottle exactly and after 4 days there was no trace of ammonia or nitrite in the tank. Because I installed a biofilter, I could actually see the bacteria on the wheel. It's only been a few weeks but I can honestly say these are the most impressive bacteria in a bottle I've ever bought.
