Do you guys ever test positive for ammonia?
I mean just a hint of it??My tanks always test for just a little....just barely noticable...no where near .25 ppm
,but not quite the yellow on the card either.
If I didn't really really study the color difference I probably wouldn't notice at all...But I'm sure its there,however slight.
The blue for the nitrites always stays true blue and of coarse I always test positive for nitrates in each.
You guys ever notice it??
