I wonder why the ammonia is 0.27 mg/l?
What could cause this? If Trout can tolerate .2 to 2ppm, I am definitely all ears!
Good question. In a normal recreational pond you shouldn't have any ammonia readings unless it's extremely fish heavy, plantless and algae free, like a swimming pool.
Respectfully i wouldn't want any ammonia reading with trout. Not sure where Bill got those numbers. Trout are extremely sensitive to ammonia. That said, it's the unionized ammonia you need to be concerned with and with your near neutral Ph it's probably quite low. I'm sure that number is Total ammonia NH4 vs. unionized NH3
Could be an error. Doubt your iron reading is correct if you sent it in. Has to be done on site. Got a similar reading to yours from a lab when in reality it was 2.5 mg/l (well water).
