any PO4 is always a problem with hermatypic organisms. just because someone is able to counter the affects of PO4 in the water column by running their lights longer or with higher intensity does not make the fact that the zoax are in charge instead of the coral.
if inorganic phosphates are kept under control, then there is nothing wrong with keeping them under point source lighting for only two hours and with indirect lighting for as long as you care.
MikeTR- why on earth would you think that algae not growing is a bad thing? think about what you have just said. was everything going fine until you started trying to feed more to get algae growing? algae is a horrible nutrient export method. it just does not work. algae leak almost as much phosphates as they take in. phosphates is not much of a building material as an energy source. organisms just change the form of phosphorous in order to create the energy needed to perform biological functions, then release it right back. that whole ATP synthase thing. in order for hermatypic organisms to perform photosynthesis properly there has to be extremely low levels of phosphates. if not, then the corals start by turning more brown, if things progress, than growth slows until the coral starts to RTN because the phosphates have gummed up the calcium pump used to perform photosynthesis inside the coral. the skeleton is a byproduct of photosynthesis.
