How well is your protein skimmer working? What I'm asking really is how much yuck is it pulling out? If you aren't getting anything then that may be it.
There are things that I did not mention doing and left out because there are people who will say that it either is not a good idea or would make no difference...but I ran my tank with no GFO
after I did it and still had no phosphates.
#1...I had a very deep sand bed. While doing research, I had read on another forum where someone else was having issues like mine. They removed their deep sand bed and went BB and eliminated them. Soooo...I got rid of my old sand bed. I divided it up and siphoned it out over the course of a month. I left it that way. I still have BB in that tank but will add a shallow sand bed soon...something I can easily and thoroughly clean as the live rock is my main source of bacteria.
#2...I did a process called "cooking live rock" that I found on the Internet. I just actually finished with my last 4 rocks...did it in stages...be sure that you eliminate ALL possibilities before you do it because its a pain. Lots of water changes...
With a tank your size, I'm guessing eliminating your sand and replacing with new dry sand would be a pain.
