Fish load and planted tanks

I know this may seem a little off topic, but considering that this it the 
repository of all available knowledge about planted tanks, I could think of 
no better place to ask my question.

I have a 75-gallon HEAVILY PLANTED tank with 160 watts of standard T-12 
fluorescent light, into which I introduce a standard regimen of PMDD and 
pressurized CO2. I am wondering how many cardinal tetras I could keep in 
this tank. Conventional wisdom (?) says 1 inch of fish per gallon. Wouldn't 
the accpetable load be higher in a healthy, heavily planted tank? I figure 
it should be pretty easy to maintain 100 of these beautiful fish, even with 
a couple of other small fish to keep them company.

I realize that with all of the plants is may get a little crowded, so I may 
not actually go with that many fish. The eco-system should be able to 
handle the load, even if I have to decrease the PMDD and CO2 additions.

Any one care to comment?
