I've been recommended Rowa Phos by a few ppl now, most recently my guy at the LFS. Any pros or cons of GFO or Rowa Phos?Watching enclosed video I have noticed that guy is using RowaPhos there, not GFO. RowaPhos doesn’t need to be tumbled so it doesn’t have to be used in real reactor. For GFO to be tumbled you need adjustable flow through the reactor and that particular model doesn’t seem to be able to do that.
If RowaPhos doesn't need to be tumbled could it just be put in a media bag? Is the only difference between a Rowa Phos "reactor" and that for GFO the adjustable flow option?
