Red Sea 50 lighting questions


Recommended Posts

Hello all.....


May I please have some help/advice/input with regards to transitioning my tank from PC's to the Red Sea 50 LED.  My current vision is reef dominated with predominantly soft corals and LPS. I may add in a couple hardy SPS down the road. 



-15 gallon high tank (20" x 10" x 18"), 10 gallon sump

-Currently powered by 60 watts 50/50 PC's

-tank is a year old


Currently stocked with:

-leather corals

-clove polyps


-Pipe organ coral



-trumpet coral

-tubinaria coral




1) How do you decided between 20K and 23K settings 

2) What would be my max( percentages ) of blue and white lights at the end of the acclimation period?

3) what percentages of blue and white lights should I start the acclimation period with?

4) How long should my acclimation period be?

5) How long should my ramp up and ramp down time be?

6) How long should I have my lights on? Currently my lights are on for 8 hours


Many thanks

Sorry that I can't answer your specific questions.  However, in general:

  • Spectrum is often considered personal preference.
  • When increasing LED light, limit changes to 5% a week.
  • Ramp up and down might lessen the chance of startling fish.  However, I consider it more esthetics than necessity.
  • 8 hours of daylight lighting is fairly common.  You might lessen it just a little to compensate for the additional ramp up and down cycles.

No need to be sorry, thanks for the input. Personally doing research about the hobby is enjoyable.  Do you have an websites or youtube channels you would recommend ?

BRStv has some good content.


Wet Web Media


Live Aquaria has a lot of info in fish species.


There are a number of good sources depending on the topic.  Plus, there are other forums, but this is a great one with lots of information to dig through.
