Are koi sensitive to ammonia?
Luckily, koi and goldfish as well as many aquarium fish are quite resilient and can withstand low ammonia levels for a few days without any adverse effects.
How fast does ammonia poisoning kill fish?
The effects of ammonia burn usually do not appear until two or three days after being exposed, although rapid increases in ammonia can cause sudden death in the fish.
What should the ammonia level be in a koi pond?
Ideally pond ammonia should be as close to zero as possible, as the chemical is very toxic to both goldfish and koi. If you have a pond with goldfish or koi, you will also always have some level of ammonia; a constantly produced by-product of fish waste that just can’t be avoided.
