I have a new lighting settup in my tank. IT's got a 65 White light and 65w Blue Acintic lighting , however you spell it haha. Anyways, soo I have a timer light strip that has day and night settings. I have the blue and white plugged in during the day and the blue by itself at night. IS this right? Should there be a period where there is NO light at all? I have a Green algae growth on my tank walls so I'm wondering if I have to much lighting.
