I've helped out in a small microbrewery that carbs that way. They cold crash the beer in the fermenter, purge the brite tank, and then transfer through a filter into the brite tank. Then they set the pressure to 4 psi IIRC, and bump it up1psi every ~hour until it reaches serving pressure. It then sits at serving pressure overnight and is ready to be served or kegged the next day. They have the stone mounted semi-permanently, and CIP with a spray ball. The brewer said they take the stone out and valves off periodically for a more thorough cleaning, but I don't know how often.

The brewery I work at does it carbonates in a bright tank with a carb stone before serving. pretty much the same procedure as JuanMoore described. Anything specific you would like to know?

How often do you clean the stone besides the caustic clean. Also as you are carbing it does the psi gauge on the cpi ARM go up as it carbes. I am wondering because i had my lone hooked up to a co2 tank and ran the line to my carb stone on bright tank and it was set at 18 psi but the gauge on the cpi arm never moved except when I gave it head pressure .

We are still under a year old, we haven't cleaned the carb stone yet besides the regular CIP. Probably going to do a more thorough cleaning on all tanks here in the near future.

The psi gauge on the arm goes up almost immediately after we turn on the CO2 to the stone. We let it run until it is at serving pressure and turn on the head pressure, let it sit for a few hrs and it is fully carb'd.

When I hook it up to the carb stone and hit it with 17 psi the gauge on the cpi arm dosent move so do you think my stone is screwed. I know the gauge works but wondering why it isn't showing the increase on pressure . Carbed it for 2hr and its been 2 days and still flat.

yea, sounds like something is not working as its supposed and the CO2 is making it through the stone. Not sure what to suggest you do at this point. In my set up I would probably transfer the beer out to an empty, sanitized vessel and pull the stone clean / replace as necessary.

Did you try testing the stone in a bucket to make sure there was flow through it before installing? Do you have a good check valve installed in the gas line right at the stone to prevent beer back-flowing into the stone and clogging the pores? Is the stone new or used, and is it SS or ceramic? Are you sure the stone is properly assembled?

The stone is old I'm sure. U haven't checked the stone myself because the head brewer dies all the cleaning they haven't showed me that yet. I have inky worked as the assits for a month or two so when he gets back I'm going to go over it with him. We only have two bright tanks so I can't transfer and check because they are both full at the moment
