I'm still on the biopellet bandwagon. Been using them in the 225 reef for well over a year but they did very little until I suffered a pseudo tank crash and ended up with some nitrates. After I had readable nitrates on a test kit, I could visibly see the pellet level dropping in the reactor every few weeks.

I also suffered a major bryopsis and turf algae outbreak immediately after firing up the biopellet reactor. However, the tank was fairly new at the time, being only a few months old and most of the problem algae seemed to be located on the Aquaroche man made live rock so this could also have been source of the problem. I took the biopellet reactor offline for a few months to see if this was perhaps the source of the outbreak and the algae problem persisted and possibly even got worse lending further credence to the biopellets not being the cause of the issue.

I've read about a few cases where biopellets caused a massive tank crash. I'm not certain what these systems nitrate and phosphate levels were prior to running biopellets but I'm assuming after the initial bacterial colonization of the biopellets, higher levels of nitrates and phosphates were fairly rapidly stripped from the system causing major RTN or color loss in predominantly SPS corals. Never heard of anyone losing any fish until this thread though.
