Reef LED 90

[joco]

Need help determining what percentage of blue and white light on a reefer 90 LED to equate to a 150-250 par for my 100 gallon tank. Newbie since 12/21

Welcome! That will be hard to determine based on tank height, rock scaping, etc. without an actual PAR meter.

With any new light , start low and build up . I recommend 35% blue and 10% white and gradually increase to 75% blue and $30% white and see how it balances and how corals are responding

Thanks a bunch. Will try.

Welcome aboard, look to local reef clubs or LFS to borrow/rent par meter.
If none, start low and work up as your corals look.
Good luck.

Welcome - agree and depending on were you are in the "ugly cycle" and what you want to do with algae, would favor blue and back off on whites as vetteguy suggests. and should rent/borrow/acquire a PAR meter...

hope to hear more from you

Welcome to the PAR-ty. I am sure there are people here with experience with that light that will be able to help.

Welcome to Reef2Reef!

I don't have a par meter but I run my 90s at 98 blue 15 white. When new items are added I use acclimation feature for 5-7 days from about 50%

Welcome to R2R! Sorry can't help on the LED.

 

[Anemone_Fanatic]

Welcome to R2R! I would recommend starting at 50% blue, 15% white.

 

[joco]

Thanks everyone. I’ve been at 80 blue 20 white for quite some time. All is good but I see algae build up on sand a day or 2 later. Thought I must have too much of one. Doubt is an everyday occurrence on my part.

I would go with the default 20k setting with acclimation mode on, set to 30 days for 50%. The RS90 is reef spec. I would turn off the moon mode initially.

I can’t help on the lights but welcome!

Welcome! If you look in the lighting section in the forum you might find someone who’s posted their numbers in the par database. You’ll see a Dana Riddle thread.
