so i mounted the marinelandon the tank (5in above the tank) and the tank just isn't anywhere near as bright as the 29 was. and it doesn't seem to matter how high or low the light is it just looks dull.
Probably an illusion.. When I first got back into fish I had a Marineland "puck" that I thought was fairly bright at the time.. When I bought my 40 and designed my own light, I moved the 20gal to a different location and put the same puck above it.. looks dull and really weak.. The light didn't change. My perception did..
