Could you possibly PM me or point me to a thread that shows me the Brite Tank method you're using the Sanke for? I have 2 Sankes in the garage, with just the spear removed for fermenting and bulk aging and I'd like to see how yours are set up.
Haha, it's really simple, and not really much of a 'brite tank'.
1. I put my sanitized sanke into my 'lagerator' (just a huge chest freezer that I keep kegs for lagering, conditioning, and waiting to be tapped).
2. Purge Sanke with CO2.
3. Dump Gelatin mix into Sanke (let bloom for 20 minutes at room temp, then heat to 170 to pasteurize is the process for gelatin).
4. Rack beer on top of gelatin.
5. Replace sanitized spear.
6. "Lager" it for a week or so.
7. Jump from keg to another keg:
Put your tap on it at a low pressure, don't tap it yet.
I have a twisty sanke tap, it's super easy to "turn on" or "turn off" Not sure about the normal taps. Either way, I put a 6 ft sanitized hose without an end on it on my tap.
Tap the keg and the murky gelatin beer will come out. Just do this enough until the line clears, "turn off" the tap when it clears and put it into the receiving keg. Ramp up the pressure a bit or else it'll take forever.
When you notice it's getting close to empty/full, watch for the hose to turn murky. This is where a nice long hose helps so you don't get any of the junk in the new keg. "Turn off" the keg tap when it goes murky.
8. Replace spear on new keg, and clean the old one!
Sorry if that was wordy, or wasn't really what you wanted, but it works for me. I've got a keg of commercial clarity beer that I don't have to worry about agitation
