Anyone know of any testing that has been done on any of the GFOs? It could be that they are all the same or that they are quite different.
I think most carbon is the same in terms of performance but some seem to leach PO4 into the water. I doubt any GFOs leach PO4 into the water but perhaps there is something else they release. Maybe not.
I've recently been running a TLF reactor w/GFO (not phosban). I think I need to change the GFO, was wondering if Phosguard is any good. Can I put it in the reactor? or leave it out in the flow in the sump somewhere.
At Bulk Reef Supply you can get 35lbs. of GFO for over $600. We sell Brightwells Extrax Phos 50lbs. for $200 or Seachem's Phosguard 20L for $210. :scratch:
I've actually never used it before. I've used the Phosphat-R which is like coffee grinds, a little difficult to work with. Maybe someone can chime in on this?
