Default 400w MH over 75g tank. Overkill???

how deep and what are you keeping? It's going to throw a lot of heat, do you have good AC or a chiller? Auto top off to handle the evaporation?

Default 400w

A friend of mine has a 400 over his 72 bowfront and it's been good for him.Clint

Still setting up the tank its atleast 2' deep, planning to put acro's and different kind of softies. no auto top off but if really needed will set-up one and I have a old chiller I can use for cooling. so do you guys think 400w will be ok.

What are the dimensions of the tank? Is it a 4' long tank? What are you planning on using for a reflector - this can impact how effective the MH lighting will be.
