Even thought I filled my Q tank a little more than 1/2 with water from my main tank and used a bunch of the bio balls the nitrite is still spiking. It's been around .8-1.0 mg
/l for the last day or two and I'm starting to get worried. My LFS
said fish can handle high levels if they increase gradually for a while and I shouldn't worry until the fish start acting really stressed out. They also said it should finish the nitrite cycle in about a week from setting up the tank because of the water/bio balls from my main tank. Does any/all of this sound right?
