Raceway

i have seen that some coral purveyors use raceways to move lights continuously so as to not need as many lights, would this be an option for smaller systems? And also where can they be purchased? I have never seen the issue brought up on the forum, just wondering

I have only ever seen moving lights used to avoid continuous shading, not to gain extra growing space with less lights. Do you know where you heard about this? I also generally see the term raceway used to describe the style of shallow/narrow and long tanks used in coral or other aquaculture.

Yes, raceway refers to long shallow tanks with linear flow. What you are referring to is a light mover rack. I use one to reduce shading from running 3 kessils on my 180g.

I know they use them at liveaquaria with radions, maybe it is for shading, I was just curious if anybody else uses the same setup

Arguably I am able to get by with fewer lights due to the mover. I have large colonies in a SPS dominant 180 and get by with 3 kessils along with T5, which is less LED fixtures than what would typically be recommended for a full SPS tank of this size, but I can’t say for sure it’s a dealbreaker (the T5s do a lot of the work). I do think it helps with shading caused by branches of large SPS colonies shading lower ones.
