Question: Will running 2x 48" Ray 2 DS on top of my tank be too much light?
My tank is 60"x18"x24" (24" deep, 18" front to back)
Height from the top of the tank to the substrate is 20.5"
I inject CO2 (well over 30ppm), and I do daily EI dosing KNO3, KH2PO4, and CSM+B.
The PAR chart for the Ray 2 (through air) is here:
(I would be switching from a 24" Finnex Ray2 DS on one side of the tank, and a 48" T5HO 2-bulb fixture across the center).
