Hi Grim,
I know the thread is old but, but please help me.
Do you think is possible to illuminate a custom 48''x12''x12''(h) with 2x54w, good enough for most exigent corals?
I'm considering usin JBL reflectors (those like seagulls wings) maybe 5'' above the water.
What combination would you recommend?
(here giesemann os URI/UVL is easyer to buy)
Thank you guys.
