Actually no. It's a peninsula tank sitting as a great room divider between dining and living room areas. Spillover was a huge concern for me, which is why I decided to try the Reef Breeders. They are well diffused and I get almost zero spillover. My recliner is positioned directly beside the tank, parallel and within inches. I can comfortably watch TV with the tanks lights on, no problem!do you get a lot of light spill mounting them that high?
