thanx for chiming in mosaic. i'm going to try to find a copy of that book soon, sounds like a good read. i'm curious about where your tank is set up... for instance, how far away from the window, how many window's, does it get direct light all day or is part of the day indirect...??
and does anyone know approximately how many
wpg natural light would supply? i'm sure it varies through the day, but lets say at high noon for a 30
gal. is it even measured in watts, or does it change to some measurement i'm not aware of?
