Fish-in cycling: what level of ammonia/nitrites is toxic? .25 OK?
 
I'm on day 26 of fish-in cycling for my 46-gallon. There are 6 comet goldfish in there currently.

I have been "seeding" the tank with media and decor from my cycled tank. I have been keeping the ammonia and nitrites in check with large water changes. Is .25 OK until the tank is cycled? My fish seem to be doing fine.

Thanks. :)

.50ppm is when ammonia and nitrites become harmful. 40ppm for nitrates.
