So my wife got me the BRS dual reactors for my birthday. With carbon and GFO on the way. My 90 is cycled and ready to go. ATM though it has no livestock. Is it ok to get the reactors online now? Or DI I need to have a bio-load before they will do anything? For what it's worth my CUC will go in one day next, week prob tues if it arrives, and I will transfer fish/corals from the other tank the following week. Thanks in advance.
