T5 lights operation time

[kamiru]

Hi,

may i know what is the recommended hrs to on my T5 lights?

I am currently running them for 12hrs per day. Would that help?

Is it recommeded that i use 2 atinics and 2 20k(aquablue +) for my 20G SPS tank?

Kamiru, you would need the 10kk bulbs in the mix too. Using just actinics and blue+ will not cut it. I would run 3 10kk and 1 20kk (recommended ratio 3:1). 12 hrs per day would be good to start with.

When I ran T5's I used a 2 blues and 2 10K and it was a nice quality.
