Ammonia from old decorations?
I pulled out some old decor, and rinsed a bunch off. I put some in the tank, but the ones I didnít, I noticed after a little while had a really strong ammonia-type smell.
I tested the tank, and the ammonia levels seemed to increase from .05 to .1 in the span of an hour.
Iím going to check it again later, but I was curious if anyone had anything to say about this?
