Which Do You Use, Blue Elite Chemi Pure ?

[427HISS]

I haven't used either, just activaed carbon, but want to try something different.

What are the differences and when to use either ?
Use full time or when ?

We meet again.

I'm a Purigen / GFO in their own reactors junkie.

But if I finished a treatment then I use GAC to absorb the med.

I typically used GAC (ROX 0.8) and GFO (from BRS).

GAC absorbs mostly organic matter.

GFO reduces phosphate primarily.
