Trace Ammonia Levels

Hi All, Here’s a question I’ve alway wanted to ask :-
My pond has been running now for several years. I use a Seneye to monitor the parameters.
I have always had a ammonia reading hovering around the 0.01 ppm region. Currently its sitting at 0.012 ppm.
I am assuming this ‘trace’ level is caused by the constant ‘cycling’ present in the Pond and is normal.
I do get some fluctuations with pH increase/decrease during the Summer months but nothing of concern.
Any thoughts ?
Added a pic of the current readings.

@Hampalong I’ve never had a reading of 0 on the Seneye. It’s been as low as 0.001 on occasions.
I haven’t really noticed any changes in readings during the 30 day ‘slide life’ duration either.
