ok i put my ammonia levels to 8ppm because im fishless cycling and it went to 0 ppm in about a week,waited for the nitrites to drop and they did and there wasnt a a big spike of nitrates, so i was like ok, and then i went on vacation and my brother added and added ammonia to keep the bacteria alive, and when i came back he added a little to much ammonia so i took some out,but before i took some water out i took a nitrite and nitrates test and there was 0 nitrites and 10ppm nitrates any1 know why there wasnt a big spike,not heavilly planted,almost postitive its completly cycled because i put 2ppm of ammonia and went back to 0(this was right before i went on vacation) and when it hit 0 i added more ammonia and went on vaca and my bro added ammonia while i was gone, so am i safe to get fish or should i double check and add some ammonia in to make sure or whats going on?
