Corals dying

If the bacteria in the biopellets are really using nutrients according to the redfield ratio, they use 16 times less phosphorous than nitrogen. You can have very low Phosphate levels and still have nitrate reduction taking place in your pellets. If you're really worried, you should start with a very small amount of GFO so that the levels don't plummet to zero in a few hours (that's good practice anyway).

Yeah, but if I have 0.02 to 0.03 Phosphates atm and >25 Nitrates (which could mean 100 for all I know) I would almost like to increase my phosphates in the short term to reduce my nitrates faster. Or at least I think I do.
