How much higher? Keep in mind I have another fixture that I am using the whites with. You can kinda see the fixtures here.
I hate to say this, but looking at your tank and you saying its over a year old... you need to find a way to purchase that Vipar...
I dont know if you are taking a photo with the iphone, but even so this looks too blue IMO. (but also seeing your daylight numbers it makes sense)
When looking at the tank in person, your tank shoudnt "look" blue. Unless you just like the bottle of windex look. But, with that will sacrifice some growth.
From my personal research (and watching BRSTV investigates) CurrentUSA is great for nano--small tanks. Once we get to the 50g range, it just cant put out the PAR that is necessary for coral growth, and in this instance more is not better.
In regards to adjusting your numbers to try and see how that will help with the nem, there is no need to ramp the red & green. Immediately crank those babies down to 0-5% for daylight. They can be present in the daylight and sunset, but chances are your room ceiling lights will give off enough to supplement what is needed. With your red and green being higher this could also have been some of the issues with your algae outbreak. Chlorophyll loves the red/green spectrum (ie why you see 'grow' lights as purple-ish-- they are mostly blues but have a larger abundance of reds too). So if you want to naturally inhibit algal growth, red and green are the first to go.
With the white, and me personally using the CurrentUSA, you could start with 10% whites and be just fine. Keeping blue at 100%. White on the Current is not as intense as other black box LEDs that have vents on them. The slim design of the Current has the CON of limiting output as to not overheat the system. Because, even though they are LEDs, they are still light and light will always emit heat because it is never 100% efficient.
So, for your new light settings,
Blue-100%
White-5-10%
Red- 0-10%
Green- 0% (I dont even know why green is on here TBH, i wish current would have integrated a UV instead or a different wavelength of blue).
This slight adjustment to the front and back should help with the corals as well as the nem. I know the nem is of upmost concern but this should benefit all.
progessively up the white by 1-2% weekly until you get to 20-30%
This isnt the CurrentUSA, but it is a visible wavelength to try and help explain why green is just blasphemy and should never be put on a customization.
