ammonia trace

[Texreefer]

i have a trace of NH3 showing up in my tank..NO2 & NO3 are undetectible
i have not changed feeding, have done one small water change a week ago, not missing any fish or inverts.. nothing showing any signs of stress, just curious what ideas you guys come up with assuming the test is accurate

any chance of contamination with cleaner (like glass cleaner)?

[Texreefer]

thats an idea but no cleaners go anywhere in the fish room. any containers i use are new and have never been used for anything else

If you have a sandbed, its possible that you might have some dead flow areas that are collecting detritus? I guess that same scenerio could occur with bare bottom also. Just an idea, ammonia doesnt just appear for no reason.
