GFO??'s

Granular will be smaller then the pellets giving more over all surface area and will work better. But with the small granulars its easier for some to get out of the reactor or bag you are using (happened to me.)
 
Hmm I wonder if pellet GFO should be called PFO lol

I use BRS granular stuff in my phosban reactor..
 
It depends on the pellet. There is a local brand which pellets are very very small and has a large amount of surface area. Other brand of pellets are much larger than granular.
