/IME it can be done as a SPS
, clam, and zoo tank. I have over 13 wpg
on my tank. It's a 55 gallon w/ 2x250w MH
and 2x110w VHO
actinics. All my SPS
are in the upper 1/2 to 1/3 of my tank and are doing great. They literally are growing out of the water-the tips break the surface. Light acclimation and the proper corals are the key. Softies and many LPS
will not appreciate that amount of light. As mentioned heat will be an issue also w/ only 10 gallons of water.
FWIW I have a colt coral, which are known as "low light" corals, growing in the upper half of my tank right under a MH
