Couldn't get my new tank to work so bought this thing a few weeks later. Followed the directions and the very next day the ammonia dropped to zero and the nitrates became legible. Nitrite never jumped, ammonia always showed zero. Suddenly the aquarium was ready for fish! I keep it on hand to use after big water changes, treating the tank and whenever I clean the sponge. I think it also helps to "seed" the new sponge or new filter material.
