I use a fermzilla to ferment my beer in but when I try to do a pressure transfer half way through the transfer it like nucleats (not sure if that is the right word) all the crud all of sudden bubbles up and dirties up my nice clear beer what am I doing wrong? I wish I would have video taped it but here is a picture. Thanks

I have a jumper hose and connect the keg to the fermzilla and it starts out fine. For example yesterday every thing was going fine and then halfway through the transfer all of a sudden it started bubbling up from the bottom. Maybe change of pressure? Am I supposed to keep pushing co2in as I take out, that's not what I was doing I was letting the pressure inside push out the beer
 
I just did a transfer yesterday and this is how I do it: First, raise the level of the Fermzilla to a countertop or table and then put the keg on the floor. Connect the the liquid post of the Fermzilla to the liquid post on the keg and then connect the gas post of the Fermzilla to the gas post of the keg. Assuming that you fermented under pressure, the flow will start if the pressure in the keg is lower than the pressure in the Fermzilla. If the pressure in both are equal you will have to lower the pressure in the keg by pulling the prv for a second to get the flow started.
 
^That. Alternatively; If you're trying to transfer to a keg with both keg and fermzilla on the floor, you need to put that spunding valve on the keg and connect your CO2 to the fermzilla and apply continuous pressure. The gravity method allows you to save CO2, but either way; the total volume of gas and beer between the 2 connected vessels must remain constant or you're just having CO2 precipitate out of the beer.
 
Ah ha thank you gentlemen I will try that on the rest of what is on the fermzilla. I have another 2.5 gallons waiting for it settle back down

From what you are describing, it seems that the CO2 is coming out of solution due to not enough head pressure. Once the pressure in both vessels equalize it will start to flow, but it's important to keep Positive pressure in the fermenter to keep that from happening. Kind of like when you have a foaming issue when tapping from a keg and you turn the pressure down thinking that's the problem. When in fact you are just creating another problem!!!

Sounds like the CO2 is coming out of solution (Beer) do to having too low of head pressure. You need to keep positive pressure in vessel you're transferring from!!
 
If you have that spunding valve on the fermentor, it can't keep the pressure as you lose volume (transfer beer to the keg). It will keep a MAX pressure, but has no control over the MIN pressure. So must be at about that point of volume transfer the pressure in your fermentor gets too low and... Burp
 
Instead of using your co2 tank to add pressure, try making another jumper hose with co2 disconnects on both ends. As stated above, the gravity method works best, especially when the pressure in the fermzilla is slightly higher than the keg (my go-to is 20psi in the fermzilla, and 10psi in the keg). Let the transfer start with just the beer transfer hose until it starts to slow down; then attach the co2 transfer hose to the IN post on the keg, and the other post on the fermzilla. That will keep the pressure constant, and save you co2. It takes a bit of practice to get right but once you have it down, it works a treat.

Cool thanks I have a beer in there right now to try it on
 
When you spund your beer, purge the receiving keg. As the beer is warm during this late stage pressure might be say 25 psi.
Then disconnect and cold crash the beer. Once clear and ready for transfer the fermzilla will be at a lower pressure than the keg note this pressure.
Try to put the fermzilla on table and receiving keg on floor.
Purge your lines ( easy to do from keg).
Connect gas to gas pressure will equalise.
Disconnect one end of gas line.
Connect beer to beer and use prv on keg briefly. Beer will flow.

Then connect gas to gas and pressures will stay equal.
No need for supplementary CO2 if the gas and displacement balances.
If the flow stops, Disconnect the gas add gas to fermzilla at or slightly above the earlier noted starting pressure.
Beer will flow and then reconnect gas to gas.

When transfer is done you can use the gas in fermzilla to purge the sanitiser out of your next keg.

So you connect the gas posts first, then (after the gas equalizes between the vessels) connect the liquid posts? I've had issues like the Op when I first started pressure fermenting and just pushed with co2 from then on. I may try this next time I do a full batch.

After the pressure equals in both then.
Note you need to disconnect the gas line and start the transfer by lowering pressure in receiving keg.
Then reconnect gas to gas.
It's a pressure balanced siphon.
