I don't have the room to run both filters on the tank. I have to remove the Whisper 10i and put the Marineland on the tank. I put decor into the tank months ago from my 37g, so there is a bunch of BB in the tank. I worry that floating the 10i filter media in the tank and I doubt it'll fit into the new filter. I get the new filter in a few days.
I think everyone is mistaken about where the good bacteria is. It is located "Mostly" where there is high water movement and O2 (media, BIO wheel, ect.).
There is some on the tank walls, decor, ect. But most is where there is lots of flow (filter media). Floating the old media in the tank is useless.
Tanker, I'm with you, but on a well established tank, I've seen where people have completely swapped out the filters with no ill-effects. There was enough BB on the tank's hardscape to carry on as usual.
My point is; Everyone's mileage will vary based on tank size, stocking, condition, maintenance, etc.
