Lighting

[jvalencia]

Just started a SW reef tank 3 days ago.How much light should it get a day. I have coraline

We have our actinics and 50/50's come on at 9am. The others (10,000K) are set for 10am. The 10,000K shut off at 8pm and the last of the lights go out at 9 pm. We have timers set for all of our lighting and our coraline algae is covering the back glass in our tank. 12 hours of lighting (for us) but 10 hours of bright "daylight".
