So im changing the media in my 60gal hob. My filter is currently holding 2 carbon slides ans 2 blue plastic slides. Im putting in tidal matrix, sponge, tank floss on one side. I was wondering if it would be more benefial to put chem pure green by itself on the other side? My LFS sold it to me said it could help lower nitrites. If not ill just put another sponge/tidal matrix bag/floss
