How did you come up with the number 40 across the board? And the UV for night mode might just be for looks. I would wait until corals are acclimated to play with that.
White: 20
Violet: 30
Red:10
Green: 10
D-Blue:50
Royal: 50
UV: 20
Lunar set dB to 5% minimum. All others off
Yes 50% is good, but watching your corals closely is even better. Any change to them and adjust Accordingly
After your tank has been running the lights for a couple of months, when do you start to increase the numbers? Do you keep increasing them month over month or not really? Corals look to be doing well in the tank.
It's all about the corals and how they react to the light, if they look great but growth is slow, increase numbers. Know your corals and how much light they require.


Like to join the Hydra club. I ended up getting the Hydra26 and I must say it's a beautiful light.
Now I just have to figure out what would be the best numbers to go with for my tank (15gal 24x12x12) which is what I'm confused with. Everyone posts they're numbers but not everyone states the size and depth of their tank which I"m sure makes a huge difference. One persons setting at a tank with a 24" depth is not the same for another's with a 12" depth. I'm guessing is would be half?
Right now I have the light 11" off the surface and depth to the sand bed is 9.5"
Right now got various corals including SPS and would like to get more.
Any recommended levels? These are my current setting and this is with a 40% acclimation period of a month. Before this I had (2) 55W 10,000K / 03 Actinic Compact Florescent Lamps

Thanks......I think...LoL
I built this nano about 10 years ago and is sat dormant with only the pump running for circulation for the last 4 years before I revived it.
The 40% is of those current settings. If you look at the graph on the left is shows the actual % numbers.
You cay White 20%, UV 10% but you lost me as you say white again at 10%, did you mean Green/Red?
Would love to get one of those new style rimless nano tanks. Have to measure the cabinet it's on to see what would fit.
