Newby here, so bear with me as I try figure this out.
I've seen people say that, when switching filters, you should run the new one alongside the old for a month, then you can safely remove old, as there will be enough BB in the new.
But if amount of BB is determined by ammount of waste in the tank, ie it grows or dies back depending on availability of ammonia, surely putting 2 filters just means that they will share the amount of BB needed to process that tanks bioload? And so the new one will have some catching up to do when you remove the old?
Would it not be better to stick the new filter in a bucket with a heater, and do a fishless cycle on it, adding ammo?
Or do I have it wrong?
