I like having both!!!!
Flouresent lights for the bulk of the lighting (bright even light)
and small spot lights in the evening to produce shadows
in the tank............the flor...would be off when the spot
lights turn on.....
the shadow effect makes for a great tank in the evening!!!!!!!
the planted tank is pretty high light but not real high... the qtank is highlight... the gsp tank is medium light.. the 75 is pretty low light but it sits next to a window.. the 60gallon snail/shrimp tank is no light but its outside and covered with duckweed...
