I have a 75 gallon with 50 gallon barrel sump. I am using duel 250W 20k metal halides with 1 65W actinic. I have had softies forever but a couple months ago got the great idea to convert my whole system to SPS oriented. So kinda started from scratch with no real colonies. Been alot of ups and downs in the tank learning zeovit and that SPS require alot more attention to thrive. But within the last 2 months I think I've mastered it and now the corals are booming
