How are my PAR Numbers?

[cleverbs]

I am switching my LPS tank to an SPS tank so my last step was to upgrade my lights. As I have said I got a Hamilton 3x 250w Radium MH 4x 80w T5HO Hamillton 460nm Blues with an M80 ballast. The tank is a 220g. I just wanted to see what everyone thought of my Par numbers. are they high enough to put SPS anyplace I want? what are the best PAR ranges for SPS?

SPS will do fine with PAR numbers over 200. But I think PAR between 350-450 is best. I generally like to see PAR from 400-500 at the top, in the high 300's in middle, and 250 or so on the bottom.

Maybe I will lower my fixture down a bit more.

I was also thinking If I changed my t5ho bulbs out I should get some more par. I would think switching from 4x Hamilton 460nm blues to 4x ATI Coral+ would make a jump in par.

When I switched from ati Blues to coral pluses I really didn't notice much of an increase in par, granted I have the t5s about 10in above the waterline. The color looked better with the blue plus though.
