I have a 37 gallon tank that has been running for several years with a dwindling group of turq. severum. I handed off the last fish today, and am hoping to find a group of young festivum for the next epoch.
So I have a choice..... stick the biowheels and filter medium in a bucket with the old water for a few hours while I tear down and clean and set up the tank..... or take everything out of service, and start over with a "dead" tank that then has to cycle for a month?
If this were your only tank, what would you do? Thx!
