I'm not familiar with that product, sorry.
If you use the API Test Kits, you will very likely still get an ammonia reading. The Seachem tests are able to distinguish between ammonia and 'bound' ammonia (often in the form of ammonium).
That's very rational. I don't believe that this is a big deal but I know people (often mods/leaders) might get up on their high horse without even noticing. Note that Fishlore is incredibly strict compared to other forums.
