Ok so now stuff gets going. I'm waiting for the results on the main tank to settle but I also saved the ammonia test tube from earlier and did an ammonia test from where I get my water for water changes. On the left, we have the water from my 10 gallon I showed you earlier. On the right is the water which I get from my bath tub to fill up my tanks. It's very similar in cooler.
You cannot store NH3 tests. Once complete (takes 2-3 minutes to develop), it must read and then tossed out. It does not keep even 1/2 hour. Please, provide a photo again of your 10 gal, 80 gal, and tap water side by side, all 3 fresh, including the reference color chart would be helpful too. Better light of the fluorescent day-light kind of a bulb would also help.
Same for nitrites too.
