I recently ripped out most of my sand (but temporary glass tub of it for wrasses). I also raised the lights to 8", which helped with the disco effect I was seeing. The stratons put out so much light, it decreases the overall shimmer when just the kessils are on. But adding these, it is like turning the lights on in what was previously a dark room.I would love to see a vid to get a better idea of the shimmer this combo is putting out. Its obviously adjustable as you're getting solid par/spectrum/coverage from the stratons, but I'd love to see what you ended up with! BEAUTIFUL setup btw!
