Hi all! Im a newbie with 2 tanks a 100 gallon and a 10. Both numbers are the same in both tanks. 180GH 240KH 7.5PH 0NO2 160NO3 what do I do now

Well, 160 nitrate is really high. Are you doing any water changes? Do the dead fish have any marks or coloration/discoloration?

Woah. 160 nitrate? That's really high. What filtration are you using and are you doing water changes?? Is the tank cycled? What are your ammonia levels?
