Hi all, this is the fixture I currently run over my tank.
I measured par on this fixture a long time ago, par was about 270-290 where my acropora sits under my 40g breeder so that’s about 12 inch from my acros ( 4 inch from water surface. (Without 2 XHOS led bars added later on)
Now I only run MH 4 hours a day, however, with MH turned off, even with XHO supplement, I think the par isn’t enough except for the 4 hours
BRS did an video stating that one xho/T5 produce around 85 par at 15 inches. Won’t I be really low on par then? Should I just change to prime/radion now that I have the funds available??
I know there are many sps dominated reef keepers doing the 4 hours MH. But doesn’t it seems that 4 T5 spreaded that far apart without MH on really produce significantly less par?
