I have purchased an IBC tank and am about ready to put all the plumbing together connecting it to the 9 grow beds. My system is in a green house and modeled after Wolfracers. My questions are:
1. Do I need to clean the tank? It looks clean, but smells like it was steam cleaned. Should I clean it with something else to make it safer for catfish?
2. Do I need to filter the water when filling the tank for the first time? or just let it sit for a couple of days to let the chlorine evaporate, before adding a few fish?
3. How long do I need to let the system cycle before adding plants?

Any suggestions and comments will be appreciated.
