Is "Tetra Treatment" the full name of it? Or are you talking about Tetra Lifeguard All-in-One Treatment?
If it's Lifeguard All-in-One Treatment, the active ingredient is "HaloShield" -- which is also known as 1-chloro-2, 2, 5, 5-tetramethyl-4-imidazolidinone.
The info that I found says it ingestion by
HUMANS is unlikely to cause significant problems, "but consumption of large amounts may cause stomach upset and irritation."
