CO2 systems for planted aquariums?

I have a 150 gallon heavily planted tank and it’s filled with the normal variety of plants: Madagascar lace sword, onion plant, java moss, java fern, Anubias barteri, cabwoman, valisneria, etc. For the past 5 years or so, I’ve been supplementing the tank with carbon rich fertilizers to support growth. However, recently I’ve been looking into CO2 injection systems, as a way to promote better plant growth and provide more stability for the plant. I just want to know whether it’s worth investing in one (as they are quite expensive), and what might be some other effects, if any, of implementing a system?

If you don’t want to jump straight into the several hundred dollar (even as much as thousands of dollars), you should really consider a carbon block instead of pressurized carbon… It takes up far less space, is just as easy [if not easier] to regulate, is FAR cheaper (name brand only costs about $150, but brandless will be about $50), and a single block will easily provide sufficient CO2 for a 150 gallon tank… However, if you do decide to add CO2, be sure to minimize surface agitation [if you don't already]– surface agitation will oxygenate the water and release CO2 into the air. Feel free to contact me if you have any questions.

That is the basic idea of what I was suggesting, though not necessarily that brand.
