From what I have seen so far on it. I put mine in the 3-5' deep zone and it almost disappears. If anything, I see the tips of it. I hear it will accumulate periphyton on the surface which should mean that the bright green will change. The green doesn't glow or look out of place in my personal experience.

I guess the other nice thing is that the weights on it aren't too heavy. If you don't like the place it's installed. Grab it up and move it a little deeper.
