Hi Chingchai , you tried in you your previous tank 10000k with T12 actinic , and with recently tank 20000k ( and you have deeper tank ) , did you thing if you use 10000k with T12 actinic will show more natural colors for the corals and you have more lights to puncture the water to hit the deep corals in the down of tank ?
10000k with T12 actinic will definitely present more natural look.
Also more light penetrate into the tank and better growth rate.
But now I prefer this combination.
I am very pleased with the look of my overall corals.
