Bit of a problem here, I think. I'm new to fishkeeping, and like a fool, I rushed into it. I followed the instructions that came with my tank (mostly) waiting a couple days to put fish in. The day after I put them in, I learned about the nitrogen cycle. So I got a test kit and found that my ammonia levels were about as high as they could be, in the "Dangerous" realm. I know there's supposed to be a spike in ammonia at the beginning of the cycle, but how high can it go without causing serious injury or death to my fish? Is a good-sized water change every day or two going help? Or do I need to add something to the tank as well? Thanks for any help you can provide.

water cnhanges really helop buyt make sure you dechlorinate it and let it set for a few hours to get close to the tanks temp to avoid sending fish into shock

Welcome to FishLore! It's great to have you with us! First off, please read the beginner articles by the link in my signature. Next, what type of test kit are you using? We like the Aquarium Pharmaceuticals Master Test Kit, because it's economical, accurate, and contains all the tests you need to get started. If that is what you are using, please post the actual levels of your ammonia, nitrite, and nitrate levels. Also, tell us what size tank you have, what fish you have in the tank, and how long it's been set up. While you are getting all this info together, a good water change like Wolfgagn suggested of at least 50% would be a good idea until we know more.

How much ammonia your fish can tolerate depends on what kind of fish, as well as what the pH of your tank water is. As a general rule, I would not allow the ammonia to climb above 1.0 PPM, though less is even better. If your pH is higher than 7, then do not let it spike above .5. Daily water changes will help keep the levels down until your tank finishes cycling. You could also add a detoxifier to give the fish some added protection. There are several out there that detox ammonia and nitrite both...many of us use and recommend one called Prime.
