Hello guys, so I bought this big reactor from http://www.amazon.com/dp/B001MXERRQ/?tag=reefs04-20 and I was just wondering if anyone uses it? I wanted to run GFO and GAC in it, I was wondering if it had to be placed in a specific order like GAC then GFO or the other way around. I was also looking at this GAC and was wondering if it's any good, I think a cubic foot is a good about if I'm not wrong, says shipping weight is 27lbs http://www.amazon.com/dp/B0017677O8/?tag=reefs04-20. And lastly, does anyone know when Tony Vargas' book is coming out? Thanks in advance. Fortunato
