Fluval lab series phosphate remover in my reactor?
 

So I have some fluval lab series phosphate remover and I was wondering if this would work in my reactor after replacing my gfo. My gfo is due for a replacement and I have this stuff. I also have some bagged fluval gfo stuff and I was wondering if that go in my reactor as well? Any thoughts would be great!

Thanks!

The other stuff I have is fluval clearmax, I was hoping they could be used in my reactor :)
