Review on 🐠 ATM Aquarium Products: Freshwater Colony Nitrifying Bacteria for Effective Aquarium Maintenance by Wendy Barents

I'm not sure about this product. I tend to overdose on the nitrifying bacteria a bit (e.g. stability - I could drink from the bottle with no side effects; it never kills my fish). However, I bought this product new and added 2-3 times the recommended dose as I am used to. The night before I trained with Stability and the next morning I woke up with half of my shared tank dead. Killed all my Denison teeth and a few rainbows. I noticed when I poured it into my aquarium that there were some tiny white clumps but I never paid attention.
