Here's my 1 watt per gallon, non CO2 injected tank:

But didn't you say your tank was 125 gallons or something like that?

1 watt per gallon for a 125 gallon is a different story from 1 watt per gallon
for a 65 gallon tank (which is very high for its "footprint").

However, I agree that CO2 isn't necessary. My 2.2 wpg 29 gallon tank is so
much easier to maintain than my high-light planted tank. There's no algae, the
plants look very nice, but grow slowly, so there's less pruning and replanting,
it needs less fertilizing, no CO2 system to maintain, etc.
