You need to do multiple water changes today. Your tank doesn't seem to be cycled with nitrites that high.

When was the last water change before today, and what fish are in the tank?
You need to do at least a 75 percent water change, then retest I would change out another 35 gallons.
50% water changes should be done every week unless there is a toxin spike like right now
Yeah I hear you. That's what I use, and my tank is 125 gallons. And I do 75-80 gallon water changes every week! It will certainly build your upper body strength! Look at the bright side!
Plus, your fish will be happy and healthy. the feeders will get eaten eventually. I use minnows for feeders, and one guy stuck around for 5 months before he disappeared.
