It depends on your tank dimensions. If you have a narrow long tank, mounting it up higher would cause some light spillage from the front and back. For my 235gal display tank (72" x 30" x 24"h), I have them mounted 15" but I do get some slight light spillage off the left and right sides but I'm too lazy to remount them.I’m curious why it looks like the majority of people are mounting around 8-9 inches. Anybody going higher say 10-12”?
@danlu_gt maybe I missed it, but your lights continue to get compared to Radion G4 which also seem to provide what has been generally accepted to be the optimal LED spectrum with the AB+ program. I have no doubt that your lights can match or get very close to what Ecotech has done. But it would be very helpful if you provided the settings to match. In addition, par values and spread in that spectrum. PLUS show us all what you get beyond the AB+ that the Radion can or cannot do besides cooling and design. What in the spectrum is going to provide better overall health for our coral and tanks in general? I’m loving what I see so far from your product and even referred to them being “sexy” in another thread. Many like myself need that extra boost of data driven information to help us over the fence. Love it or hate it, the work BRS does to showcase the lights they sell shows a clear picture of what you should expect to get for your hard earned money.
You will still able to support your corals with 2 ReeFi Duo Extreme if you place the SPS in the right location but for even coverage, you should get 3 Extremes in perpendicular to your tank length. Check out the 2nd picture from few pages back, we installed 3 Extreme at my LFS Red Sea 650 peninsular tank:Just curious, looking at upgrading to a 60 x 24 x 18 lagoon tank, not SpS dominate but some nice ones. Am I going to be looking at buying 3 extremes or should 2 be good.
