our job as brewers is to make yeast happy and krausen is the magical little critters' way of letting you know that you're doing your job.

Doesn't look like it's slowing down either.. there is a steady flow of foam going through the tube.
would suggest not doing anything, at least for this batch. let it run its course.
then, for next time, you'll probably need a bigger fermenter. or a smaller amount going into your current one.

Yes I have an autosyphon, but my airlock is a one piece airlock that has a lid on top wont opening that run the risk of infection in the beer?
a three-piece airlock works good for blow off. just use the bigger piece and, like Big Floyd says, stick that 1/2" tube inside on the part sticking up and krausen can escape that way.
only ways to avoid having to use a blow off tube is a bigger fermenter or smaller volumes.
