Hi, all! I just recently got a 40-gallon breeder, which is where I'll be moving all the fish in my 10 gallon into. My question is, how long should I cycle it for? My dad (he kept Oscars about 30 years ago) suggests a week without fish, would that be enough? Should I do it with the fish in or out? Put in safe start or no? This is my first time having a tank larger than a 10 gallon, so I really don't wanna mess this up.
