Florish Excel, better Hmmmmmm....

Is florish excel just as good as co2 injection. It probably isn't but would it give a good outcome just like co2 injection.

It's better than no carbon, but it's not as good as CO2. Some plants are sensitive to it. Fortunately, one of those is algae, so some people use it as an algacide.

I use it, but I haven't seen any exceptional growth from having used it so who knows how effective it is at supplying co2.

Flourish Excel is a dilute solution of glutaraldehyde, amongst other things (that are kept a commercial secret). It does not supply carbon dioxide in any way to plants.

It is not a direct substitute for CO2, but is better than no carbon source, as mentioned.

No it's not as good. Better than nothing but there's really no comparison. For years I used excel and then finally went Co2 first as DIY then pressurized. With excel my plants grew okay, with CO2 the growth exploded. You can have a nice tank with just excel and even without it but if you want to be able grow anything that peaks your interest the right light and CO2 is where it's at.

I think I read somewhere that the glutaraldehyde just provides a food source for bacteria who metabolize it and release co2. don't quote me on that though

Definitely not as good as real co2.

If you have a tank with plants that do not require co2, it will help, but not as much as co2. If you plan on keeping something that really needs co2, I would imagine excel causing minimal success at best.
