Aha!  A chance to support the hypothesis that Paul Sears and I have
been working on.  Instead of trying to remove the phosphate, add (yes
add) light (you've only got 120W for a 180gal tank, correct?), K2SO4,
KNO3, and trace elements to the tank.  The idea is to make sure that
your plants can consume all the available phosphate, leaving none for
the algae.  I can help you with dosing, but you'll have to find the
ingredients locally.

Incidentally, my guess is that the phosphate is coming from the tablets, not
the peat.
