What I have been using with good success is Purigen and Chemi-pure combo.
The ion exchange resins in chemi-pure help with phosphate and metals.
I do like the Purigen/Chemi-pure combo as well...then used the chemi-pure elite that has GFO
in it with good results. Just don't like how chemipure fits in my reactor. Restricts flow from the size of the bag.
Either way, I believe the want to use Purigen was for a money saving choice due to limited budget.
EDIT: That said, one doesn't even know if you need to run any type of media in a system before it is set up. It might not need any of these things.
