My system is somewhat new so the verdict is still out on the light movers. I went a little more crazy after loosing my job in May and built the system. My pond is 10 1/2" deep and have egg crate resting on 1/2" pvc frame. Running a photo period of 9 1/2 hours. Most coral doing well LPS, zoas, palys, with the exception of SPS specifically my millipora, but of course the system is still relatively new. My millis come from my display tank and flourish there. But everytime I frag and then move to frag pond it either looses all of its color or RTN's. All other parameters are similar in both systems. My purple tip acro looses it purple tips. My slimer, and purple poccilipora seems to be satisfied. Actually for my SPS I have added a second eggcrate shelf about 4" above the pond bottom to get closer to the light which is about 19" above the water surface. Got the ideas for the pond from a thread on another reef site. A lot cheaper than a glass or acrylic tank. John you are welcome to come over and check it out. It is far from a perfect system.
