So I have 4 of these over my 180 mixed reef and I love them but the shimmer is just waaayyy too much...it literally looks like a disco ball going off in my tank and I was wondering if there is anyway to tone the shimmer down? I have already tried messing with the surface water and fixed that the best I could, but it's still not great. Is there a lens or screen or anything that would help with this? I literally can't look at the tank because it has so much shimmer it makes me almost sick to my stomach...any ideas or opinions??
