Sorry, just trying my best to follow along....
Yes, I popped the top of a canister that has been sitting full of dirty (seeded) media and water for 4 months and the water at the top was 4 ppm.
I only have an XP3 running on the tank at the moment. I can only assume the ammonia concentration was up in that filter too, as they were unplugged at the same time. I added ammonia to make around 2.5 ppm for the tank, but with what was probably in the filter the overall concentration may be as high as 3 ppm.
Tomorrow night I'll post test results.
