I have two Reef Flare bar lights 90cm long paired with a 4x39w T5 fixture (2x blue plus, 2x coral plus).
The reef flares are on for 12 hours at 100%, and the T5 on for 12 hours also. The lights are mounded 20cm above the water line, and all Acropora are growing 40cm deep from the water line. So the lights are mounted 60cm above the Acropora.
Some of the Acropora are paling in colour, where as some are looking okay. Growth is slow. Nutrients are 10pm nitrate and 0.03ppm phos. 11 Chromis and one two spot bristletooth. Alk is at 7.7dkh and calcium 425ppm. Coralline everywhere.
I don’t have a par meter, but based on others experience is this enough light? Could I me over doing it? Any suggestions?
Cheers,
