Flourish Iron VS Flourish Excel

[got_nailed]

I had been using Flourish Iron but last week I was sent a bottle of Flourish Excel. I know most of you’ll are using excel (that don’t have press-CO2).

So what’s the difference?
I don’t think my plants like it as much…
Any info would be helpful on this.

Flourish Iron is an Iron supplement.

Flourish Excel is a Carbon supplement.

They're not all that similar and aren't interchangeable.

LMFAO

How did I miss that? I guess I grabbed the wrong bottle last time I was out and didn’t pay any mind till last night when I opened the Excel up and did not know it was clear.

I should be shout for this.
