So that is the issue then 😱 CO2 dead gap in the aquarium not a lighting problem 😵 
so if the CO2 bobble diffuser push all the bobbles up, how is the water circulation will bring them all the way down to the substrate if they are stay floating on top, how much water circulation do you need to bring the CO2 down.
But i will do a CO2 test on the subs this weekend
