danthenewreefman Posted February 6, 2011 Share Posted February 6, 2011 Most of my rock with SPS is about 6inchs away from the water surface and will be at maximum 12inchs away from the Par30 bulb. ---- question: I'm thinking that I should use one with 60optics for the middle over the high section of the rock? Seems like 40degree optics would be a way too bright and way too tight at that distance? Link to comment
