Blowoff on Secondary

So yesterday, after a week in primary, I racked my beer over to a secondary (5 gal carboy), and added my dry hops (1oz. whole leaf amarillo and .5oz citra pellets). Everything went very smooth, and I was really pleased that I had the perfect amount of beer to perfectly fill the carboy just below the neck (as on my first batch I was quite short).

So I pop my airlock in, put the carboy in the corner of my room, and go to watch some television. About 2 hours later I come back and the airlock is full of beer and some had leaked out the top. So I pop the airlock and bunge out, throw them in some sanitizer, clean up the little mess, sanitize my thief, and take some beer out. I pop the bunge back in, jam a hose (sanitized) in there and run the other end into a milk jug with sanitizer solution, and make a blow off.

Now today after I come home from work, I notice the beer has come all the way up to the bunge and a little beer is sitting in the middle of the hose.

My first question is, what should I do now? Is it okay to leave this how it is, with the beer up to the bunge and beer sitting in the hose? Or should I take the same steps I did when I made the blow off and clean out the hose and take some beer out of the carboy?

Second, why is this happening? The beer level is actually rising, its not like this is foam from fermentation activity. Could it be from the whole leaf hops expanding? If that is the case when they expand dont they absorb beer? Or do they just expand more then the volume of beer that they absorb?

Has anyone had this happen to them before? Did I take the right steps in dealing with the overflow?

Sorry for such a long post, and I really appreciate anyone who could give me some advise on what to do next.

 

I think this is what is happening, I do notice little bubbles and foam around the hop sack.

 

The yeast definitely took off, and I did take a reading before racking. Had a 1.055 OG and 1.012 FG. When I racked the airlock in the primary was bubbling about once a minute.

 

Yeah theres tiny bubble rising and gathering around the hop sack causing some foam, and then there is a stream of tiny bubble going from the hop sack up the neck of the carboy causing a thin layer of foam right up underneath the bunge. Some foam comes up through the hose everyone in a awhile, which has caused some beer to be sitting in the middle of the hose.

So you recommend leaving it like this until the bubbles have subsided, and then just pulling out the hose and popping the airlock back in?

Also, is it okay for that beer to be sitting in the hose or should I move the hose around so that the beer flows into the sanitized solution in the milk jug?
