This is exactly what I run mine at(I also have the pro, run my white at 35%). Tank is a IM Nuvo 20 peninsula. Light right on top tank. Growing Monti cap at about 9 inches down, Monti digi,Anacroporia,birdsnest and stylo growing from 7 inches down and above that. Acans, candy canes and mushrooms on gravel bed growing good but the Acans turned orange from red.
If I had to do it over I'd buy a more powerful light----which I just did---setting up a IM Nuvo 10 as a QT then using it as a frag tank--I bought the AI Prime 16HD for it. With the Prime I can run much more powerful blue light with less white and get more PUR.
