Confused as to what to do.

Through trial and error over the past 9 months I came to the conclusion that my system just runs better and i have no issues if i continually run RowaPhos. Everytime i took it off big problems. Well now the issue is it’s been in there so long i have a huge amount ( i think) of biological filtration that has built up in my reactor. So much so that it is blocking the flow of water. So the time has come. Do I? Toss all media and spongers inside and reload the Roa? Or do i take it offline and sink the reactor in my sump and start another reactor. Or is the benefit of what i believe to be a lot of filtration not really happening ? Here are some pics.

I run rhowaphos 24/7 and it’s the best single thing I ever added, and like you have found, it prevents problems, certainly in my case and looks like yours as well. Keeping phosphate very low is good in my experience and the recommend level is around 0.03ppm

It needs changing by the looks of it, if that’s what you mean, it looks a little clogged but the pictures aren’t that clear.

If you are worried about removing a potential biological filter (I think that is what you are asking?) I wouldn't worry about it. Assuming you have live rock, you have plenty of filtration. I would clean it out and replace the media....making sure you keep up on it going forward lol

If you are concerned about the loss o biological filtration just reace the rowafoss and feed lightly for a few weeks while the bacteria developed in other parts of your tank.
