If as you've said previously there is absolutely no sign of stress, one of the numbers (ammonia or pH) just can't be accurate.
What about AmmoniUM?
I also found out (just did a water change and I don't know why i didn't think of this before) that the water from our bathroom is 1.0-2.0 ppm ammonia. Before today, I would rinse of the filter cartridge in that water. Today I used the kitchen tap which is the one that reads 0.25 ppm ammonia for the cartridge. I always use the kitchen water for the water changes and condition the water.
Would rinsing the cartridge in 1.0-2.0 ppm have a large effect on the tank? I'm not going to use that water anymore, but I was just wondering.
Going to check levels soon once the water has cycled through the filter.
