Yes this is what I am refering to, distance from water level to lamp.

I think actions with these speak louder than words. I am happy to have optics fitted for you but you very seriously dont need them, we have one client running the Metis at 60% at 24" full dominant SPS system. The client with the 30" tank is running at 85%

I will ask Pacific sun to clarify better for you
