Enough Light?

[Mr.Yuk]

I have 4x96W PC's over my 75G reef. 2 are 10000K white and 2 are 10000 actinic. I have a nice spot about 6 inches below the surface where a clam would fit well. Do you guys think I have enough light for clams, and if so, what about T. crocea?

not enough light for crocea. they require the most. i would recomend a derasa or squamosa for the powercompacs. i just sold a 6 inch derasa that was kept under 4x55watt in a 72 gallon bow. it grew from 1.5 inches in about 3 years
