SeaChem Multitest: Ammonia Test Kit

This kit measures total (NH3 and NH4+) and free ammonia (NH3 only) down to 0.05 mg/L and is virtually interference free in marine and fresh water. Free ammonia is the toxic form of ammonia (vs. ionized Ammonia NH4+ which is non-toxic) and thus it is much more important to keep an eye on the level of free ammonia in your system. This kit is based on the same gas exchange technology that is used in the Ammonia Alert and thus is the only kit on the market that can read levels of free ammonia while using ammonia removal products such as Prime, Safe, AmGuard and any similar competing products. The other kits (salicylate or Nessler based) 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 rerelease the ammonia, thus giving you a false ammonia reading.
  • multi-cavity plate for simultaneous testing of up to 6 tests at the same time
  • sensor based, sensitive to less than 0.01 mg/L
  • includes reference for test validation
  • marine or fresh water
  • Range: 0.0 - 6.0 mg/L
  • Precision: 0.01 - 0.1 mg/L

New Aquarist Savior

As a new aquarium owner cycling a tank, I was alarmed every day by outrageous ammonia readings that should be killing everything in my tank. But all life was healthy. Daily water changes, massive clean ups, and yet, off the chart ammonia. As a new Aquarist, all advice I would get on forums is I was a terrible fish keeper, and my tank must be filthy, even when it was sparkling clean!! No one tells you that high end water conditioners fix ammonia and make the nessler tests fail miserably. Thank you Seachem, for making this test, and saving my sanity.

Welcome Relief

Been fighting ammonia problem with daily 40% water changes for a week; replacing water with prime treated tap water. VERY glad to see 0% FREE ammonia with this test. Still trying to get total ammonia down but we are breathing a bit easier now.

It works

I was able to tell how much NH3 ( free amonia) I had before I added ammo-lock, and how much was still toxic, AFTER I added ammo-lock. It also proved ammo-lock works !
