Starting CO2?

[penguinexdeus]

I want to try out CO2 in my tank. Plants have been in maybe a month, showing some new growth.  Got a cheap kit on the way, and also bought some of those CO2 tests.  Question is how do I know how much CO2 I should put in or what the rate should be?  Do I use the tests and try to find a sweet spot at some number to shoot for?  If I start using CO2 and stop will I get a lot of melt back? Hoping the co2 will give me stronger healthier plants and boost growth and get things really established - or am I looking at things wrong?

So I was told to install it and turn it on the slightest amount possible. Let it run 25 hour and test. If more is needed step it up. And continue that way till ur at a nice level and you aren't in dangerous fish death waters.
