im actually currently using 2 aqueblue special, 1 blue plus, and 1 kz fuji purple and i like the color im getting its not super blue but its not just white either. getting good color and growth with it as well. but i mostly have zoas/ pali and a few LPS
I used to run a 4 bulb configuration and I was a fan of two Blue+, an aquablue special, and a UVL Actinic white. This was before the purple+ bulbs were available, so I never got the chance to try them out in the mix, but they seem to be very popular.
