What Leigh said!
I am taking today off work to go shop and build a CO2 system. I have
55 gallons Moderately- Heavily planted with about 2.5 watts per
gallon and for 3 -4 weeks now Algae has consumed all of my time! The
plant growth slows to a halt and the algae takes over. If it is
possible to ballance this out with any significant plant growth and
without CO2 I can not figure it out. If you back the light off to
control the Algae the plants stop developing. And if you do not the
plants run out of CO2 and stop developing leaving the Algae to take
over. Either way the plant growth slows to a crawl and the Algae is
my tanks best producer.

Actually I don't plan on doing injection. At least not at the start.

Do not go over 3 wpg without CO2 injection. In fact, staying close to 2 wpg
would be better. Just leave some of your lights off until you can get a CO2
system set up. (Compressed would be best for a tank as large as 75 gallons.)

Too much light without CO2 injection will be algae hell. Worse, it can cause
pH swings extreme enough to kill your fish.
