which is your favorite phosphate reactor

I've never had a BRS but I've heard gfo media can slip through the filters. Have you guys not had this problem? I still like my TLF reactors even though the build quality may not be as stout as BRS. And aren't their reactors dual meaning you can only have one pump working on both reactors? Carbon needs a higher flow rate then gfo and carbon needs to be replaced more often. Not bashing anything just bringing up some thoughts.

I dont run GFO anymore but when I did I used a BRS reactor and dont recall having issues with the GFO slipping through.

I wouldn't suggest getting the dual reactor, you are correct, GFO should have a slower flow rate than carbon. IMO GFO should not tumble because it can break down easily and get back into your system. Carbon can have a light tumble. 2 reactors would be the ideal solution, if not then you can just have the carbon chamber with slower flow in the dual reactor.

I thought you had to slightly tumble GFO to prevent it from turning into a single large clump?

I wouldn't tumble it. GFO is soft and can break up pretty easy causing fines to get into your system. When I ran it I would get it to where it was just visibly tumbling then I turned it down a tad until it stop tumbling and ran it that way. You are right though boogs, it will clump together without the proper flow, this typically happens in media bag instead of a media reactor.

Cool. Not to go too far off topic but why did you stop running GFO?

Actually my understanding of it is quite the opposite. GFO should tumble but very slowly so that it doesnt clump but also slow enough so that it dosnt fine . Carbon is softer than GFO and should be packed tightly so that that it cannot grind and create fines. However firmly packing the carbon probably would require a bit more flow than one would want running through the GFO so in that respect it makes sense to have separate pumps or flow rates.

Yep that makes more sense to me

Carbon is soft as well and should not be tumbled vigorously. I do a real light tumble, I turn it up till it tumbles then down until it doesn't tumble then slightly up again.

You have to be careful with GFO if tumbled too much, I've read that it can cause "pop eye" in fish. Don't quote me on that, just heard that through some knowledgeable guys. You can easily crumble GFO in your hand and carbon much less so.

I put enough flow through the GFO to barely tumble the top layer. I pack the carbon tight between
two sponges. I've NEVER had the GFO go through the reactor. The two little fishes reactor uses sponges
above and below the media to keep it contained. The BRS reactor has the same type of sponges above
and below the media but the good part is that the media is contained in a plastic removable tube that goes
inside the outer housing. To clean the media chamber you just remove the inner tube and clean it out instead
of trying to wrangle the enire reactor underneath the faucet.

Yes I tumble my GFO at the lowest possible and have my carbon separated like Zooid said. Ever since I have been running my reactor 24/7 I have got better coral color and have almost no more algae.
