Shouldnt be too much once it is stocked and the tank has some diversity.I currently have a 12 hour photo period, including an hour moonlighting before and after peak intensity. LED Lights turn on at 11am and off at 10pm, so ramping from peak intensity from 11am to 1:30pm and then it starts to decline at 8:30pm. My T5 lights kick on at 12pm and off at 9pm. It’s about an hour more overall lighting compared to my old tank. Is that too much? I used the radiant color template by ecotech
Did you dose phtyo to the tank at any point? If so, how much?
