Should I leave it or take it off? I put it on thinking it would mix the colors up so each coral gets a even amount of white and blue. There was a ton of shimmering (a ton of white and blue spots going crazy) without it and now there isn't (just one color and not much shimmering), so I think I accomplished what I wanted.
Is this better for coral, worse or will it have no effect?
The tank is a Biocube 29 (the leds are only a couple inches off the water) and the light is made of 20 xre royal blues and 10 xpg cool whites.
