Do theese parameters sound normal???

I had red sea and ran into issues where the tests didn't match the strips I used and weren't consistent. I also had a horrible experience with Mardel strips. The Mardel ammonia test told me I went from 0ppm to 6.0ppm within one hour of testing...

I switched the Salifert - they have amazing accuracy; not to mention their color change and effect is so obvious and dramatic. They're definitely pricier and slightly more complex - only so far as they have a few additiona steps when mixing reagents - but they are well worth it and incredibly sensitive.
