Co2 and fertilizer?

Is co2 liquid different from liquid fertilizer?

If you're discussing the Seachem line, Flourish Excel is a carbon supplement (not as good as co2 itself but has its place) and there is Flourish comprehensive I believe, which is the general all around fertilizer.

There is no true liquid co2, there is just liquid carbon.

It is not a true replacement for injected co2 either, as it is not nearly as effective. That's not to say it isn't useful though, but gas co2 and liquid carbon cannot be thought of as the same or used the same way.

Flourish Comprehensive does not have the major three NPK

Really? I'm looking at my bottle right now... Looks like the analysis for the top three is for nitrogen, phosphate, and potash (potassium). So I'm thinking it does have them... Otherwise it wouldn't be comprehensive.

For a low light tank, Flourish Comprehensive may be all the fertilizing you need, possibly with Excel. But, for any more light, it doesn't provide nearly enough NPK to meet the plants' needs.

Agreed :-) But it does have them... Just not enough for much more than low tech tanks.
