Would the use of Prime affect or mask the test results for ammonia ? I'll retest a couple of tanks tonight and post back the results.
Prime converts ammonia (NH3) into Ammonium (NH4+) by attaching Hydrogen atoms to the existing ammonia molecule.
Aquarium grade test kits, including your API kit, reads ammonia and ammonium as the exact same thing.
If you have 2 ppm of ammonia and you add Prime, you will then have 2ppm of ammonium. The API test kit will read the 2ppm of ammonia as 2ppm, it will also read the 2 ppm of ammonium as 2 ppm.
If you have 2 ppm of ammonia and you only add alittle bit of Prime and you end up with 1 ppm of ammonia and 1 ppm of ammonium, the test kit will still read 2 ppm.
At typical aquarium conditions, the natrual state of ammnoia/ammonium is ammonia. Therefore the effects of Prime converting ammonia to ammonium will wear off after about 24 hours. Thus if you are relying on Prime to 'detoxify' ammonia, you will need to dose daily.
Daily dosages at the quantity recommended on the bottle will not be dangerous to your fish nor their ecological system.
Although I personally feel it is much safer to do water changes to keep the ammonia in check as opposed to letting it build up while 'detoxifying' it with Prime. Ammonium is much much less toxic than ammonia, but high concentrations of ammonium still are not good for your fish.
