Co2 and Flourish Excel

If I am injecting Co2 with a pressurized system, will I still need to dose Excel?

I've read around, and some people say no, while some others say both are needed.

Can someone give me an explanation on why both will be needed or not needed?

Thanks

Flourish Excel can be used alone, or used with a co2 injection system, but is NOT necessary if you're using an injection system. Because when using a co2 system your plants are getting a steady supply of carbon dioxide, Excel is a liquid carbon supplement meant to replace the need for a co2 system. Which is why you see alot of those with smaller tanks or low tech tanks use Excel because there's really no need to spend the money on a co2 injection system, and people with medium to high tech tanks have a co2 injection system because most high tech tanks have high light plants that need a constant supply of co2.

In addition to this...Excel is actually an algacide when first put into the tank.
It quickly breaks down into a compound that the plants can use as carbon.
But(I think that) most who use both are primarilly using the Excel as an algacide.

The shortest distance between any two points is a straight line...in the opposite direction...

Depending on the fish in your planted tank, Otocinclus algae eaters love diatoms.

I only dose excel in my planted nano and I've never had an alge problem knock on wood. Dose the recommended per week amount everyday.

as stated above, excel/gluraldehyde is algecide and nothing more in co2 injected tanks.
