Excel is a carbon supplement, not a fertilizer. The two provide entirely different things. And anyone can easily buy Metricide and make 1.5 gallons of an Excel equivalent for $23.For my tanks, I've found several, good hydroponics liquid ferts that work as well as the SeaChem product, without the "Glut" and are a lot less expensive.

What's the difference? We're supplementing elements needed for plant development beyond those naturally available, no?Excel is a carbon supplement, not a fertilizer. The two provide entirely different things.

Other than the way it's delivered into the tank - via CO2, liquid Excel, or just calcium carbonate through a WC - how is carbon not functioning as a fertilizer? I'm not saying it's a broad spectrum fertilizer; it's a single element but it's easy enough to dose others in a similar manner (e.g. liquid K) so I'm not clear why it wouldn't be considered a fert.NO..Excel is ONLY a Carbon source. In order to supplment elements you also need to dose Micro and Macro Nutrients. Excel is not a Fert.
So something needs to be an element to be a fert? Carbon is a group 14 element. It's symbol, "C." It has an atomic number of 6,NO..Excel is ONLY a Carbon source. In order to supplment elements you also need to dose Micro and Macro Nutrients. Excel is not a Fert.
