Review on 🚀 Fast API Activation for Optimal Nitrification in Freshwater and Saltwater Aquariums by Anna Goetz

I was struggling to get my aquarium running. After trying several similar products and having no success, I settled on this one. The vial I received did not have a blue cap. Luckily, Revain was willing to send a replacement bottle. Strangely, the replacement I received didn't have a plug either. I'm not sure if the missing lid could kill the bacteria or if the product wouldn't work even with the lid on. (I had a spare cap so the bottle couldn't be left open.) I didn't notice any change in the ammonia or nitrite/nitrate levels in the tank. So I don't think it did anything.
