Media "reactors" are pretty simple things. It is probably fine. Does TFL mean Two Little Fishies? If so, then they work OK. I have a couple. Like I said, they are simple devices - just make sure that you get all of the carbon/GFO off of the threads when you put it back together or you can get leaks. I run mine inside of my sump in case they leak. I just run carbon in mine - no GFO.
Let the turbos do their work. You should be able to see where they have cleared some ground. While they are working, then continue to change water and remove as much as you can by hand. It could take a month, but you should see improvement with the snails. Oh, are you sure that you got turbos and not astreas? Some stores sell astreas as turbos.
