Chris,
Since setting up the tank in May, my phosphates and nitrates have never been very high. I do keep a log of all my testing and the PO4 has never been above 0.05 ppm and the NO3 has never been above 3 ppm. You might ask then why start biopellets???? I like to experiment with new toys and I wanted to be proactive. So, that's how I started biopelllets. I also had a real good experience with biopellets in my old tank that I just rebuilt. What I glean from your and Mike's input is...."don't worry, be happy" for now....continue to watch closely to make sure things don't get out of hand.
I need to work more on stablizing my Alk to tighter variations closer to 8 dKH so that I can keep the SPS corals with the eco-bak. Also, I may need a little more flow. Right now I have 35-40 turnovers/hour through the RSM S650 and need to get up to 50-60 or so...would you agree?
