Great lights I also use them on my 180 except I use 6 of them. They will grow any coral I have sps lps mushrooms and zoas definitely would recommend

Beautiful tank, what height and sttings are you running?Great lights I also use them on my 180 except I use 6 of them. They will grow any coral I have sps lps mushrooms and zoas definitely would recommend![]()

Are you still using these at this settings? How high off the water and how deep is your tank?Just a quick update to running these lights. I'm still running them at 35% blue and 5% white for the last month mow and sps are still growing and everything else is fine. Ive cut about 35 heads off my big hammer on the right ad it was against the glass, I still have some frags to sell so that's what is stuck in the sand at the bottom. Or I my put them in my bedroom tank.![]()
I'm not using it at these settings now, that was an old photo, I lost all my sps due to bottoming out nitrates and phosphates, I had a reshuffle of a few corals and have worked it upto 50blue and 5white.the light is 9 inches off the water line (not tank height) and the water depth is around 15 inches to the sand. I have still got issues with low phosphates, even though I have been daily dosing it.Are you still using these at this settings? How high off the water and how deep is your tank?
Thanks! They're about a foot off the water and my tank is 2 foot deep I run the blues at 100% and the white at 10%Beautiful tank, what height and sttings are you running?
Cheers. I'm going to work the lights back up I think.Thanks! They're about a foot off the water and my tank is 2 foot deep I run the blues at 100% and the white at 10%
Thanks for the response. Would you think two would provide better coverage then just 1?
Thank you so much! I’ll probably just get two, hang them around 10” off the water and rent a par meter to make sure not to roast anything. These lights seem to be a lot of power based on re-reading through this thread! I’m new so I will start with lps/softies/zoas.One probably won't cover all the way to the edges unless you raise the light up and then you will have light spillage front to back. One possibility is to go with one light and have low light corals on the left and right edges. If you want to jam the tank side to side with high light corals then you will probably want to go with two. Good luck with whatever you decide!
I just got the larger unit (the 300w) for a 65g tank.
Is there any reason I wouldn't want to run the whites at 1%? I think the tank looks best with just barely enough white to bring out the colors in the fish, because the corals pop the most under the blues.
Current setting is 60% blue, 1% white. The whites run for 8 hours, the blues are currently running 11 hours. I think reducing the photo period may be wise, but everything is loving the light.
There may be a mix of opinions on the answer to your question and I think you have a reasonable plan. IMO, as a general rule I suggest that people watch their livestock (especially corals) and see what they like and what best helps them grow and be healthy then secondly consider what is visually appealing within the range that the corals prefer. Additionally, from what I have read, most people start with the whites at 1 to 3 with these lights and then increase them from there to a desired level.

Are there any cost effective ways to implement a ramp with these lights (other than adjusting manually)?

With Visparspectra 165w, keep in mind that they can push big PAR, mine, 8” above surface, showed 750ish, at full intensity. I run mine at only 50% which resulted in 400ish at the most.
It proved to me that I did not need to spend 4x more to get great results.
Running blue/violet channel only I would not recommend as it does not address the needs of the other two chlorophylls corals draw from. Small amounts of red/green (in the white channel) should be present, however might be considered minor.

Is that 50% blue and white or 50% blue with an amount of white? Lovely full tank. Also did you do any par readings with just blue?With Visparspectra 165w, keep in mind that they can push big PAR, mine, 8” above surface, showed 750ish, at full intensity.
