I do not get algae with higher levels of nutrients.
I like to ask where's my algae issues?

I can easily slow plant growth down using light.
Why would I do it with low nutrients which makes measuring and dosing far more difficult?

Less light= less algae, less CO2 demand and less nutrient demand.
This is a very simple concept.

But the lower you go, the harder it becomes to measure and determine what and why things are working in the water column.............

Things get recycled more rapidly and to the point where measuring the water column becomes meaningless.............

Non CO2 methods are good example...........and if you lower the CO2..........as long as it's stable...........

But the question is is it really the nutrients?
Or is it the CO2 and/or lighting?

I'd say it's the lighting/CO2.
Those drive growth..........not the bottom up(nutrients) method.
