Tank is 50 gallon and I have the light about 13 inches up. Mostly softies in my tank as of right now.Would help to know what kind of Coral's your keeping tank size & the number of lights you have. But just in general terms for the spectrum I have been running the white channel at 10% if the blue channel over lps & White at 20%of blue channel over sps. no science to back that up but that's what I have got the best coloration with personally.
I would say your in the ballpark but on the high side for softy's. It's impossible to say for sure with out a par meter, things as simple as a difference in water clarity can change par from one tank to the next. But the viper's are very powerful lights, the white channel seems very strong even at low settingsTank is 50 gallon and I have the light about 13 inches up. Mostly softies in my tank as of right now.
I'm at 10% white 30% blue right now
hi,ramp up slow ,work up to 5% white 40 -45% blue over 7-10 day period ,check all params ,if have not alreadyLooking for settings advice on the 30" model (T300) over a 36" tank.
I currently have the light set 13" above the water, with a 16" deep tank. so roughly 28"-29" from light to sand bed.
Ch1 (Blues) 30% on for 12 hours (noon until midnight)
Ch2 (White) 1% on for 8 hours. (2pm until 10pm)
I've had the settings like this for the past 2 weeks and some of my Euphyllia (Hammer and Octospawn) are looking sorta bleached. My Octo had nice dark, almost black tentacles with bright yellow tips, now many of the tentacles are almost see through and seem to be losing the darker coloring. My hammer also seems to be losing a bit of color in its tentacles too...
At this point, I'm not sure if I'm giving them too much light, or not enough... At 30% and 1%, I can't believe I'm giving them too much light.... based on reports of others, so I'm wondering if I'm not giving them enough light. Reading the forums, seems most people say Euphyllia are pretty tolerant of light levels and will adjust, so i'm not sure what to do at this point. I don't want to keep tinkering with the lights leading to more stress, but I'm really not sure how I go about getting this right without a PAR meter.
My LFS does not have a PAR meter and actually looked at me like I had 2 heads when I asked if they did....
There are no local clubs around me that have one.... BRS rental seems to be my only option for a PAR meter, but was hoping to avoid that expense.
I really didn't think lighting would be this difficult to figure out.... I sure wish my corals could talk!

I just purchased the same for my 75. What times do you have your lights set on for each channel?Obvious question, but just making sure that we are talking about the 165w. Also confirming that you have one light above the 50g tank. I'm assuming that is a 3' wide tank - does it have a center brace?
I recently got (2) 165w to put over a 75g. One approach is to start at 3 white and 30 blue and then adjust from there depending on what your corals tell you.
Blue Led's show up less on par meters. The par is really more than it reads. Depending on what meter you have.I know this is old but I'm curious everyone runs their 165 watt vipar so low but iv had mine over a 65 gal 12 inches above the water and running it 12 hrs blue 100% 8hrs white 20% and recently checked with a par meter and changing to 100% blue 50% white seems to get the right par everywhere! But seems triple what others use?
these lights are strong, dont play the par game. Its just a stupid number. I ran what you did and cooked all my coral for years with no growth and only loss. My tank is 30" deep 210 G tank, and im running 1% B and W with B on 8 hours and W on 6 hours and growth is through the roof again. Turn that crap down.But seems triple what others use?
