Hello, i dont have a timer for my lights and i turn them on at 6am and off at 6pm, the tank doesnt get much natural light. After 6pm the lights are off for the night cause i read that it is bad for the fish to get too much light. I want to be able to see the fish at night, or from like 6-10, can i turn the light back on, turn it off during the day?? Any recomendations?
