Offense And Defense

ATM Triage First Response leaps into action to address the emergency removal of ammonia toxicity in situations such as bio-filtration stalls or failures, power outages, or any other instance which results in accumulation of unwanted toxic nitrogenous compounds.  Slime coat support and healthy conditions are promoted while toxic conditions are demoted.

Neutralize And Be Safe About It

When it comes to water conditioning and the use of neutralizing agents, ATM has differs from the rest of the back when it comes to philosophy.  At ATM we believe in ever keeping attention on bio-filter health, rather than the idea that problems can be solved with chemicals.  Triage contains no oxygen depleting chemicals that are found in other products that act as neutralizing agents.  Furthermore, ATM stresses the use of neutralizing agents only when they are necessary rather than frequent functions such as water changes.

  • Removes Toxic Ammonia
  • Detoxifies Nitrite
  • Provides Mucoprotein Slime Coat Support

Neutralizing Priority

Because ammonia is typically the compound that accumulates in bio-filtration failure, ATM TriageTM First Response works with a priority toward ammonia first. As ammonia disappears, ATM TriageTM First Response kicks into its secondary function by helping limit the toxic effects of nitrite,
if present, in subsequent doses.
