Hi everyone I have just bought a viparspectra 165w, I have a 300 litre tank I have an anemone, pulsing xena, star polyps, and a pink pussey coral and fish lol. I have currently set it to 60 blue, and 1 white. Is this OK or should I have it on other Settings, also tank is 4 Feet wide and 2 feet deed. Only have one at the minute til I get another at the end of the week so it's in the middle 12 inches above the water. Thanks in advance
