Even though I really hate when you get a short answer like that. He's right. I'm gonna side with both of you for a sec then with GC.
It turns out that with lots of reading on the subject you will find that you need po4 and no3 to feed the pellets. Now If that is not maintained, via large or medium fish load you run into the problem of the pellets striping the corals to starvation.
Now I'm in the same boat as you. I read a lot of material on the subject but failed in many areas later. My main failings was not taking all other phosphate and nitrate removers off line. Then I wasn't stocked fish wise to keep up with the pellets. (Mind you I used 30% of what John Warner via telephone conversation (is that his name?) recommended). I also did not keep my alk stable and low.
Also and I think this is crucial. Once things looked super bad, I should have done a wc and took em off line.
Skimmer good, bioload low, still running carbon, Gfo, a big Refugium, and I have a large clam. When I ran Bp's my levels were almost 0's across the board.
Anywho, I f'd up and although I think in my head I figured out what I did incorrectly, I will never use the drops from Satan's anus ever again.
Sincerely,
