lighting question

[phi delt reefer]

you wont get that color for a couple reasons;

that tank is lit by leds
picture is possibly editted (saturation looks like its been increased)

want pop from your t5? 2 blue plus + 1 purple plus + 1 actinic (replace with blue plus if color looks too washed out for your liking)

you can add an exocotic stunner strip of royal blue leds to get the same pop as that tank if you want that exact coloration.
