Gurgling POC overflow

So fine. Nobody cares how I fixed it. Gonna tell you anyways.

Simply removed the air tube controller thingy majigy that everone says to put in the top air hole to adjust it. Yea, that worked well.

Once removed, the open 1/8th air hole works just fine for my pump. Nice and quiet or quiet enough.

Perhaps one needs a larger hole and larger sized air controller to allow for more air if needed ??
