Review on StartSmart Complete Freshwater for Optimal Aquarium Health, 12-Ounce by Jennifer Hulett

After following the guide, the aquarium should keep circulating. It says that the tank will not work for more than 72 hours, but this is complete nonsense. I kept adding more products because I figured I might need more. The whole bottle was almost empty and my 7 gallon tank was still not working after a few days. The thing doesn't work! He'll instruct you to add the fish right after, but the fish won't survive. I've tested the water over and over again and it's still not safe to add fish. This product is a scam and I'm sorry to say it doesn't work. It's not a miracle in a bottle, it doesn't instantly fire up your tank like it says on the bottle.
