My son's tank is experiencing a BBA outbreak on one specific plant. I have added a powerhead to aid in water movement to that area. However I would like to reduce light levels during the day to also combat it. At the moment the lights are set to come on at 7am so the kids can feed the fish prior to school, and then off at 9pm so I can enjoy the tank in the evening.
I would like to set the lights to come on at 7am to 10am on again at 3pm to 9pm, the room is well lit during the day. Southern exposure with lots of windows - no direct sunlight hits the tank though. Almost pitch black once the tank lights go off.
Do you think this multiple on and off schedule would adversely affect the fish or plants or should it be ok.
