Co2 & nutrients

[skeletonw00t]

Probably a silly question & has probably been covered before... But...

Does having more CO2 mean you need more nutrients?

Or is it only light that drives the nutrient demand up?

Or does having a tank with a yellow DC need more nutrients than one with a Green DC?

Just wanted to double check

Re: Co2 & nutrients

Light > Co2 > Nutrients.

It will depend on your current dosing. More light will cause more demand for nutrients if sufficient co2 is available.

A tank with a yellow drop checker would not need additional ferts if the lighting hasn't been increased. The demand is driven by light.
