Use[edit | edit source]

Special notes[edit | edit source]
Prime like all other water conditioners will cause most common test kits to read a false high nitrogen level. For example if testing for ammonia, Salicylate or Nessler based kits determine the total ammonia by raising the pH of the test solution to 12 or greater. At this high pH all ammonia removal products will breakdown and re-release the ammonia, thus giving you a false ammonia reading (it was probably only Ammonium). Same goes for nitrite or nitrate.
- Seachem's Multitest Ammonia kit use a different method and therefore their kit reading is not affected by any water conditioner chemical. But their Nitrate/Nitrite multitest kit will be. 
- Tip: Leave a sample of the water out in a cup for 24 hours and retest it for ammonia then. Any Prime in the sample will have gone by then.
