Okay.When I start a new tank I take a handful or two of gravel from an established tank as well as a dirty plastic plant, the new tank is almost instantly cycled, I also to this to my pond when I fire it up in the spring, I don't get an algae bloom anymore, instantly clear water, the tank sits for a day to allow and dissolved solids to settled than I add my fish. You won't be able to keep any bacteria alive in the brown water you saved and it will start to stink as the bacteria die.
