AI hydra

I was thinking of 2 AI Hydras to light a 75. Is that enough or do I need 3?

Whats a good price on some used ones, HD or non-HD

I think that 2 Hydra52s are enough light for a 75g tank. Do you have a center brace? That would block placement of a third light. How high do plan on hanging them?

Current Tank Info: 40IM Fusion, 40lbs of rock, and 20lbs of sand. Just a few fish and corals....for now.

Yes there is a center brace. I do not know how high. I like to get the mounting arms for the back or goose neck.
