I have a 90g and lots of light, and lots of plants, but no co2, i am being told I need co2. my problem it that with i don't what to shell out the cash right now, Could one of those fizz factory systems could help?
 
CO2 fizz factory probably won't even raise CO2 levels enough to see a difference in a test kit. You'd have to use so much that a pressurized system would start to seem pretty cheap.

There's no real alternative to pressurized when you hit tank sizes over 55gallons...and even then, DIY is a hassle after a 20gallon tank.
