Default Propane tank froze regulator

SO I was brewing this past weekend. Saturday morning I got up and took a few propane tanks to the gas station to be filled. I have your normal everyday tank, then one about twice the size that is ubber old. Small one worked fine for heating my strike water etc. While I was doing that, the large one started to hiss and gas was coming out. It was sitting in the sun for a few hours and thought that was it so I moved it in the shade, it stopped.

Well, I hooked it up to my burner to start my boil. Within about 5 minutes the regulator was frosted over. I knew this was not good, so I turned off the gas, disconnected then attached the smaller tank and completed my boil.

I know this isn't good/right, but what is it? Water in the tank somehow? Over filled tank??

Now, I just filled this sucker at close to $30. Is there anything I can do that won't involve loosing it all?

I googled this and there are about 1500 different "reasons" for why it occurs and just about as many recommendations on what to do. They all seem to contradict eachother, so I'm just going to wait for one of our resident "gas geeks" to give me a detailed technical explanation and then for someone else to put it in laymans terms. I remember last year at Brewtopia's holiday party that it got down to freezing and the big gas heat lamps would go out and keep having to be restarted.

The second guess, over filled tank, the relief valve opening while not in use meant that tank had no room for propane liquid to expand. The tank was sending liquid propane into the regulator where it was trying to turn into gas again and it needs heat to change from liquid to gas. Same process that chills the tank only on a much smaller and colder scale as the surface area of the regulator is so small. As to using the tank, keep the flow down for about 30 minutes and enough propane should be burned off to correct the problem of liquid propane entering the regulator.

Pour hot water over the regulator. It's just the condensation freezing on the outside of the regulator body due to high humidity and super cold propane inside the tank. Not a big deal, but hot water will clear it up if you need it to.

So I'm assuming it will stop once the propane level drops to an acceptable level?

Nope. Don't think I could stop it from rolling away if it was.

Yeah, I've heard about that happening if you have too many ports that are pulling too much propane from the tank. I don't exactly understand it. But hope that helps you.

Have you put it on a scale to see if it is overfilled?
