Too much light?
On my 75 gallon tank, I'm running an Odyssea 4x54w 48" light fixture. I have the timer set as follows....first set of bulbs come on at 12 pm and off at 8 pm. The second set comes on at 2 pm and off at 10 pm. That gives me 6 hours at max intensity and 4 hours at half intensity. I'm not running injected co2, but using Excel/Metricide for my carbon source. Is this too much light to combat algae issues in this tank? I will say that I have just learned about fert dosing (outside of the flourish and Osmocote root tabs I've been using).....& just received my macro/micro ferts in the mail Friday. So, I have learned that with the proper ferts, algae will have less chance to thrive. But for this thread, the question is regarding my light system/schedule. Thanks for the info/advice.....& feel free to answer in regards to the lights or ferts.
