The outdoor-proof CO2 setups sound great, but I don't have the money to 
buy a CO2 setup.  Especially not a two stage regulator.  I'm in school 
and I even buy my fish food by trading in plants at the store.  
Christmas moss is a great form of currency.  ;-)  I use Excel on my 
small indoor tanks.  Besides, the anacharis and hornwort in the nearby 
whiskey barrel pond grow beautifully without CO2.

I also can't grow floating watersprite in this setup and it has access 
to air.  The H. difformis fell apart too fast for CO2 to have been an 
issue.  Plants store some carbon.  I suppose I can test the carbon 
hypothesis by removing the anacharis and trying Excel.  It won't hurt 
anything and I have more anacharis than I know what to do with growing 
in the pond.

I'd still like to know if there are more winter-hardy plants that I can 
try growing.  What else is temperate that I can get through normal 
online sources?  We're a bit short on creeks for collecting natives here 
in Southern California.
