I believe that you answered your own question. Place all the fuel in one settling tank and recover all that grvitates towards the top.
As for suspect fuel, it's possible that the new fuel was problematic. Were it from a batch of poorly converted fuel that had a high level of mono- or di-glycerides these could have mixed with water in your tank to form the muck that you describe. Chances are that if the fuel was partially incomplete you would have been displacing a whitish colored smoke from your exhaust, perhaps even at idle. You would owe it to yourself to conduct a sample transesterication of the settled fuel to see if anymore glycerin settles out. That could confirm that the fuel's reaction didn't go to completion. Even if it hadn't, you could probably get away with putting it back in your tank if you knew the tank was void of water. This is yet another good argument for having tanks cleaned or at least thoroughly flushed when switching to biodiesel. It's bad enough having to deal with all the gundge that's been deposited by petrol diesel over the years. But the level of water oft found in petrol diesel and that settles out to the bottom of the tank can further exacerbate problems of an incomplete biodiesel. Should it be presumed that you are the manufacturer of the biodiesel? Or are you one of the rare few that has access to a commercial pump in Cali that is dispensing B-100? If the latter, you have an obligation to inform both the distributor and vendor of your problem.
