Red sea LED 50

Fry1992 · May 14, 2021

Hi all,

Just upgraded my lighting to a red sea led 50, my tank is currently 33x33x33 cube. The new light is part of slowly upgrading to a bigger tank.

With the new light do I need to reduce the lighting %. I currently am using 100% blue and 50% white. I have the app using the acclimatise mode but is the above too much for my tank size?

Thanks

That light shouldn’t be too big for that tank. I actually think the recommended range is 20 inches square. You probably can use 2 on that tank to make sure you’ve got enough intensity at the sides. Depends on how spread out your corals are and what’s where.

Sorry I should have stated my tank is 33cm not inches

Oh. One should do it then. I would use the same settings you have. Only way to really know for sure what’s happening is with a par meter. There should be a chart with the light. You can play with the height above the tank if you think it’s too strong for what you’ve got in the tank.

Thanks a lot, will leave it be and keep my eye on it. Cheers for the help

Your good. Side note a short acclimation period never hurts anything when a lighting change is made.

This has the red sea PAR meter readings on some basic sized tanks....running it wide open you can hit NEAR 400 PAR at the surface. There's a really good thread somewhere on here with people sharing lighting setups for this....I run mine peak on the blue at 70% at 2 hours after sunrise then a gradual decline until sundown, then it goes to zero in about an hour or so....the white is the same at 60% with a gradual peak and decline. Hope this helps. I love my light.
