Hi guys. In efforts to save electricity and cut back on algae, as well as keeping my aquarium lit during the hours im home automatically, I was wondering the following: I have 3 aquariums with 4 lights total. I am gone to work from 2:15 pm to 11:30 pm 5 days a week. I googled around and saw that fish should have their lights on for 8-12 hours a day. I have no live plants in my tank. I was wondering if I can split the 8-12 hours a day into 2 mini day night cycles. For example leaving it on in the morning for 4-6 hours and turn it off while I'm at work then turning it back on for 4-6 hours for a total of 8-12 hours a day... Is this bad for the fish? Should the fish have one consistent day and night? I want to do: 9am - 2pm on 2pm - 9pm off 9pm - 2am on 2am - 9am off And repeat. This works best with my schedule as sometimes I get out of work early at 9pm. Thanks for any recommendations and suggestions. - mike
