Would a 78 watt 1x 10000 k and 1x 450 nm actinic give me 300+ PAR at the bottom of a 12" deep tank? Or would it be better to go extream with 4 HO bulbs 2x10000k 54w and 2x 450 nm actinics 54w so basically a meager 2.8 watts per gallon or a huge 8 watts per gallon ( for sps, some acans/blastos and maybe a few nps (carnation tree/ duncans)) oh nd zoas
