how mutch light do I need for a dersa and squamosa clam in a 75 gallon? (48X18X20) Could 440 watt PC's work good?

My cousin has a dersa in a 16gal and his wattage is 9w per gallon, PC. The dersa is doing great. I heard it will do ok in a 75 with that wattage, but put a the top. Dersa and sequamosa are easier than other clam, because they live with less lighting. You will hear different beliefs from every reefers, but stronger light is always perferred.

I would leave the derasa on the bottom, as well as the squamosa. They are both sand dwelling clams. I believe the derasa would be okay and would try it first and then see how it goes from there
