currently setting up a 100g reef tank and found a appropriate 60" Current MH
Outer Orbit fixture for a pretty good price. but sadly the ballast for the Dual Actinics has died. I am now thinking about selling that and setting up my own retro setup (x2 250w 10k MH
, 2 130w Dual Actinic and some led
moon lights). My question is: The Outer Orbit was an entirely enclosed fixture with glass protecting the MH
bulbs and acrylic covering the actinics. For a retro setup do i need to cover the bulbs to protect them from the saltwater, evaporation, etc? if so what is the best way to do it?
Also, the hood sits 10" above the top of the tank (which is acrylic) with the water about an inch below that, do i need to worry about the heat from the MH
's damaging the tank?
