I use my Fluval 404 on my 75 as pretty much a big reactor. I usually run a chem-pure/gfo mix (my own chem-pure el&ite concoction) in each of the 4 trays of the 404. The other day I was wondering through Petsmart to grab some media bags for my 404 and seen that they had Fluval clearmax in stock. The info on the packaging sounded promising as far as phosphate and nitrate removal so I grabbed a few boxes to ty out in the 404. In the 404 trays I alternated like so. Chem-pure, clearmax, chem-pure, clear max.
I am interested to see how it performs, just wondered if anyone else has used it with success, the price doesnt seem to bad either.
I like it thus far due to the size of the media pellets themselves and seems to have far less dust than GFO.
