How many Pros for a 300 Gallon SPS (72x36x27)

[MstgKillr]

How many Pros would you guys recommend for a 300 gallon SPS (72x36x27). I would like something comparable to my (3) 400 MH's.

How should the fixtures placed... With the length or width?

Mstg,

I would start with 3 Radions. If you find your SPS isn't getting enough light it is very easy to add more Radions at a later time.

Very easy if my wife doesn't see the credit card statement!

If I used 3 Radions how would I orientate the fixture? From left to right I would have a Radion ever 24" but from the front to the back would be 36" that I would need to light.
