I once screwed up and put 200ppm of nitrate in a tank. I took me a week
to notice and about 3-4 weeks for the plants to eat it all up. No fish
snail or any of the shrimp in that tank was affected. I keep my tanks at
30-45 ppm nitrate.

Ammonia stresses fish, not nitrate.


120ppm killed about 1/2 of the shrimp I had for a 3 day exposure.
