Isn't having UGF on one plate and RUGF on the other going to be a bad thing?
I mean, water will take the shortest path between them, and that might mean
under the plate!  You might never get much flow through the gravel.  Granted
this shouldn't be quite as bad as the guy at work who had a powerhead on
one uplift tube and left the other tube open on the SAME plate (he 
wondered why fish were dissapearing...).

Another observation:  Anyone ever done CO2 on a RUGF?  This seems like it 
could be a potentially useful trick... The CO2 bubbles trapped below the 
filter and must diffuse through the gravel bed, just like a reactor.

This is always going to be true;  the amount of phosphate tablets required
to drop the pH is enough to produce several healthy algae plagues.  Best
to either accept the hard water or get the CO2 up & running.
