Light correlation to No3

[brianxcheng]

I was mistake n realise my led didn’t ramp up from 20% to 70%. It’s stay 20% all the time.
Also I was suffering my No3 didn’t drop.

After I found out my mistake on the light setting. N finally my no3 drop to 0.01.

May I seeking u all experience , strong light will lower the no3. Does it have correlation? Thank

No, it's not a direct correlation and is quite a bit more complicated. Strong coral and algae growth will reduce NO3 provided there's enough other nutrients (low phosphorus can be a limiting factor nitrogen consumption) and other variables are favorable, one being a system is not overfed.
