I am currently researching simular issues.
T5...T5...T5 !!!....(+) 3-5 wats per gallon actnic(+) Daylighting.(soft corals will do good on 3 or so watts per gal
.The harder your corals the more wattage per gallon you'd want to have . Day lighting can vary as long as the aforemention parameters have been met.(<<<as far as how BRIGHTLY you'd want your display during the day that is)
If you want everybody to "THRIVE" first time out...w/no deaths////no unwanted amonia and No2
spikes in your readings....T5 appears to be the closest thing to a "SURE BET".
