I am trying to figure out how to schedule my lighting....I leave for work at 7 am and like to see/feed my fish before I go; in the evening I like to watch/feed them as well. My tank is planted and I am thinking 12 hours a day is good.....any suggestions on how to set the timer? I was doing a split schedule but on the weekends I am not happy w/ it......If I left them on for 14 hours it would meet my personal needs but would that just promote algae? (it is a very low light system at the moment) 45 gallon tank w/ 40 watt full spectrum bulb...
