SPS placement under 6x54 ATI Sunpower

[db1317]

What's the lowest area in the tank that I can successfully keep SPS in a standard 75G(21" depth) tank? Currently running the fixture about 8" above the water and using 4 blue+, 1 purple+, 1 KZ New Gen bulbs. I'm asking about lights only, as I realize flow and water chemistry are key components, too. Any feedback is greatly appreciated.

I would say with 21'', as long as you dont keep your fixture abnormally high above the tank, you can probably keep sps on the sand. They wont grow greally fast, but they should keep their color

I would say anywhere too if not shaded by other corals...
I got a 8x24w PM on a 30x30x24" cube and I have about 200 par on the sand in the corners ! still under acclimatation after 2 months, lps bleached on the bottom...

Thanks for the feedback...Looks like I have more options for coral placement than I originally thought!
