Ok, now coming to the placement of the entire setup. I've had my 29g in the living room and haven't had an issue with the Kessil (since it's on a low level table).
The 40B on this custom stand together is 4' 2" tall and I tested the Kessil on it and it's super spread (lights up a lot of ground outside the tank area) and it's also disturbing to watch television now (when I'm sitting on the sofa staring at the tv, I can see beneath the Kessil and it's really blinding).
I'm in an apartment and really don't have a lot of options on placement. Any advise on how to overcome this blinding effect?
