I used this after setting up a new reef tank. The ammonia levels dropped within 5 days, and my corals stayed healthy. No fish died, and the water clarity improved quickly. Highly recommend for new tank owners.

It worked well in my 10-gallon freshwater tank. The ammonia disappeared within a week. A bit expensive, but effective and safe for my sensitive fish.
