gagaliya said:hey just curious, how did you get such high ammonia with just 6 zebra danio and in a 55 gallon tank within 1 night? did the tank already contain high level of ammonia to begin with, before you added the zebra danioos?
the tank was stuck at 4 ppm ammonia for about 3 weeks on its own....no fish...nothing
figured out it was debris in the tank from lace rock...did water chagnes to get rid of debris...and bring ammonia down
added the zebras...and bio spira
thats it
