I've been keeping planted Discus tanks for several years now.  The
solution was to automate the water changing regimen.  Twice a day about
10% of the water is replaced with RO water from pressurized tanks used
in drinking water systems.  The water slowly going in at the bottom of
the tank, by way of a timer controlled solenoid (like those used to fill
an ice maker) is room temperature so that it completely displaces the
much warmer water leaving the top of the tank via an over flow which is
plumbed into the house drain.  Just keep an eye on the integrity of the
over flow siphon to avoid any mishaps (the voice of experience).  The
overall change in temperature and PH is negligible.  The only draw back
is the increased need for regular fertilization.  If you have any
questions as to the details of the system please don't hesitate to
