my question is how much amonia is too much? i had a fish die yesterday and checked water paramaters, my amonia was at 1-2 ppm (used liquid test kit by api), is this to much, or should it always be at 0?
It should be zero. If your were cycling the tank with fish once it got to .25-.50 you should have done a water change. Let us know a little more about the tank, how long its been set up, how many fish, did you cycle it, and last do you know about the nitrogen cycle? With a little more info you will get the help you need.
the tank has been set since about march of 2009. it is 20 gallon. i havent made any changes in the past couple of months. no new ornaments or fish. it has 5 guppys 1 red tail shark and a cory cat(forgot wich kind). i do a 2.5 gallon water change every sunday. havent missed one since set up. also the tank is running a tetra whisper ex20 filter. but just purchaced a aquaclear 30.
Yup, should be at zero. I have a pack of Seachem Purigen for emergencies. Whenever you have an ammonia spike or something similar, putting it in will help filter out some of the harmful stuff. Just a tip I got from a friend.
