The readings are the same pre and post Prime. It's about .15, not dangerous but still a measurable amount.
I don't know if you've heard of it but I just ordered an ECO-Aqualizer. It's suppose to remove all the ammonia and any other toxins in your tank water. It claims to reduce tank maintenance by 75%. And to eliminate fish stress and virtually eliminate fish diseases that are caused by bad water or stress.
I have no idea if it will do any of the things it claims to do. But it has a 180 day money back guarantee. Plus has a 35 day free trial, you just pay $15.00 for handling and if you hate it send it back. If you think it may work for you, they charge you after 35 days. And then you still have 145 days to see how it works long term. Hate it, get your money back. Like it, get one for each of your other tanks.
It's a pretty safe way to try something new.
Also, thank you for taking the time to explain chloramines. Unfortunately I couldn't really fallow, I got lost pretty quickly so the rest made little to no sense to me.
Yes that stuff is very scientific. How old exactly are yout tanks, the last poster is onto it. If you can get beyond the nitrite I think the nitrates will eventually take over the ammonia.
