Review on DrTim's Aquatics Saltwater One & Only Nitrifying Solution: 100% Natural Eco-Friendly Fish Tank Cleaner, Water Clarifier, Waste Remover, Organic Reducer, and Water Quality Optimizer – 4 Oz by Stephanie Johnson

Ok for those trying to use it as a "cleaner", noting that it suffices , except for weekly water changes. This product is designed to start aquarium bacteria. I have been running freshwater and saltwater aquariums since 2003, apart from this one there are no other working aquarium bacteria on the market. I've tried more than I can count and it's the only way I've been able to provide my fish with a stable environment when the fish first become stocked for a few days to a week. A word of advice: be sure to add drops of ammonia to the water as directed. to allow bacteria to multiply before adding the fish. If you want to prevent fish from dying from ammonia in the water, this product is for you.
