Hey all. So I’m day 11 of my Dr. Tim’s fishless cycle. My ammonia and nitrite lvls were really high after adding the last dose of ammonia on day 6. Ammonia was between 4-5 ppm and nitrites were at 5 ppm. I was waiting on a heater I ordered so I could heat the salt mix for a small water change, so when that got here I did a 10 percent water change and that brought my ammonia down to 2 ppm but the nitrites stayed off the charts. I’ve been testing every day and my ammonia is now down to .50 ppm but the nitrites are still around 5 ppm. Maybe it’s 2. I don’t really know because the 2 and 5 colors look the same on this api kit. I have been testing for nitrates for around 4 or 5 days now and I was at 5 ppm and now I’m at 40-50 ppm according to the nyos kit I got. So roughly doubling every day. So I know the bacteria are working which is good. I’m excited about that. I did order a salifert nitrite kit and it should be here Saturday. I got it just to see if it tests different than the api. I can’t for the life of me figure out why they aren’t going down if everything else is reading correctly. So I guess my question is when the ammonia gets to zero what do I do. Do I add more ammonia or do I wait until the nitrites go down. (However long that will be) I don’t know how long the beneficial bacteria can go without ammonia. I know they won’t starve right away but I have no idea how long it will take for the nitrite to go down. If you read all this thank you. Thanks everyone. Happy reefing. Cheers
