Your Answer: Nitrites Correct Answer: Ammonia Score: 0 I thought nitrite was most toxic or at least thats what the lfs ppl said "A noble spirit embiggens the smallest man" Simpsons

Fish cannot handle as many ppm of ammonia as they can of nitrites. On the other hand, both are toxic enough that the difference of tolerable levels isn't that big. Still, Ammonia definitely does take the cake. -------------------------------------------- The aquarist is one who must learn the ways of the biologist, the chemist, and the veterinarian.

This is because They are already stressed by the ammonia in the water and all of a sudden a new poisin is added. Their bodies can't handle the extra toxin. It is also because the ammonia and nitrite will have a cumulative effect because the ammonia is still present in the water. I can't think of some creative metaphore but I'll try to latter. 20 Gallon Long: Aquaclear 300 2 Bolivian Rams, Mikrogeophagus altispinosus: Gumby and Pokey
