A few things about fireAde- http://www.dtic.mil/cgi-bin/GetTRDoc?AD=ADA479808 - Tyndall AFB Test
FireAde 2000 AFFF LP contained a fluorinated surfactant, similar to what is found in 3M AFFF

Look at page 5.
The first toxicity screen performed with FireAde 2000 had an unusual reaction with fish. After the fish had died the remains turned to a gel-like consistency. This result had never been observed before with any other agent. Additional analysis of the foam concentrate showed that the pH ( 12.4) was higher than the neutral pH indicated by the manufacturer. The manufacturer sent a second sample for testing and the first batch was sent back the manufacturer for analysis. The second batch of FireAde 2000 was closer to neutral; HOWEVER, this did not significantly improve the LC50 (74 to 92 ppm), indicating that the high level of toxicity was not due to pH alone.
