50G would be 48 " wide......so 250w (which should spread out 24" each way) would be minimum....actinic...I would skip...(depending on deep water corals or shallow water) depends on what you are keeping

Go with 2 175W bulbs. MH only spreads 24" x 24" total.

I just duplicated this thread a few minutes ago. Stupid me.

So ONE 250watt Hamilton Reefstar or Reefsun unit isn't enough for my 55 gallon tank?

Even with a double ended hqi system?
