What settings and at what height did you run them at? If you dont mind me asking.

I think about 12-13 inches above and started them at 50% blue and 10 white and slowly upped them to 80/25

One will get you by, two would be ideal. Make sure they’re dimmable

See I saw my best growth at 80/20 mine are only 9 inches off the water those settings were great when growing sps but I lost them due to zero phosphates,cyano, stn. Then I slightly rescaped and have lps right below the light and have turned it down to 50/3. I dont know what par they are as dont have a meter but would love to know what just blues are par wise at different settings.

At 60/20 the top of my tank was mid 300 and bottom of tank was 150

That's cool but here in the uk clubs are few and far between.

Thanks, how tall is your tank ? As those readings are about where you want them can I ask why you went higher to 80/25, or did the blue not put the par up much more.

Thank is a standard 75 gal so I think 24” tall. And I just wanted to up it some more as I talked to other reefers about their settings. I need to recheck it honestly.

That's cool. I just like to know what people are running these lights at. I think for the price they are very good.

The viparspectras will grow coral but you really should add some supplemental t5 to provide your corals with full spectrum lighting.

You're correct they will grow corals. I was thinking of adding a t5 to supplement the light what would you recommend colour wise.

 

[Jonathan Troutt]

I just started using t5 but what was recommended to me was coral plus and blue plus. Basically i have changed my lighting to be mainly t5 with led supplement to help with color pop.

I didnt want to spend a rediculous amount of money to get the proper spectrum in led.

 

[Nicholas Dushynsky]

I have been looking to add a t5 and was looking at a blue plus, just trying to bodge a t5 on to my set up.
