First off...im new to this forum and i am addicted to it...im a beginner and ive read most of the beginner articles and decided to do the fishless cycle. i got the tank on sunday and set it up and all and everything was about to buy the first 1/3 of the fish for my 20g tank when i decided i didnt want to put the fish through the cycle. so this morning i put ammonia (pure ammonia) in the tank (6ppm) and 9 hours later i tested the water again...the results dropped all the way down from 6ppm to .5ppm...i was very suprised to see a drop that significant on the first day of the cycle. i have been adding "stability" from seachem...(most everybody says that stuff doesnt work) but anyways i was wondering if that sudden drop was possible this quick and if the stability stuff might actually work. also if the readings were correct can i start to add the fish when it goes to zero?
