Can You Give Us Light "par" Readings Per. Tank Sizes

250 MH should typically be sufficient as it relates to the depth of your tank.
This also depends how high off the tank you have it.
Presumably you would have 3 of them to cover the length of the tank.
Of course, all of this is based on an assumption that you want to keep a mixed reef.
Which may or may not be correct.
