What is Chemi Pure?
I didn't want to take over a Filstar post, but my LFS mentioned using chemi pure or bio chem zorb in my filstar. The filstar came with the bio chem zorb, so I put that in, which in another thread I was told is not the right thing. Before I run out an buy more stuff I don't need, I thought I'd ask what the chemi pure is.
Thanks so much for the info!
