LOL, you guys are too much.
I tested par off my fixture thanks to Brian for letting me borrow a PAR meter.
1000-1200 right above water center to MH
600-800 right below water
450-600 at the level of corals 10" under water level
250-300 at the floor
220 at the front left and right corners (floor of tank)
Numbers seem really good to me. Looks like the 250w radium 20ks on an hqi ballast push almost as much as what I've seen of the 400w radiums on a electronic ballast.
