Is anybody using or know of a light timer/timer that I can use for a weekly cycle with 7 days of programability? I have my lights start coming on at 4pm so my tank is lit for when I get home from work until I go to bed. But on the weekends I want to be able to view my tank in its glory earlier and shut off earlier as I'm out. I'm not ready to jump into the full tank controllers yet, I just want something for my lights. Thanks in advance!
