new 40 gal tank, saltwater, LED. Which spectrum is best to use throughout the day and evening? With it on bright all day I have developed an orange/brown algae/bacteria. I was told to shut it off for 3 days and it will dye off. I'm on my second day and it is looking amazing. I'm afraid to turn the lights back on. Any suggestions?
I have been using fluorescent lights for years, low cost and work great. But in the last bit I have been looking at LED. I like them but the start up cost is a lot higher but over time it would be cheaper.
But like has already been said don't do incandescent they don't work as well have will cost you more.
Unless you have photosynthetic life forms in the aquarium or you are working with seasonal reproduction methods the ramping up of your lighting period is for personal aesthetics only. There are some fish with sensitive eyes that can be startled by sudden bright lights but most of these fish adapt to the lighting routines of our tanks.
