Blueflu1 The Acan Reaper! Jun 3, 2009 #2 What do you have in the tank for corals etc.... Some corals require higher light. I normally keep my lights on for about 7 hrs a day for the metal halides and the t5 actinics on for an hr before and after.

OP OP T tank202094 Non-member Jun 3, 2009 #3 I only have live sand and fish. Should I kept light on for 5hrs in the morning and 5hrs at night or live it on for 8 hrs straight?

Bobbofin Non-member Jun 4, 2009 #4 I run my 420 & 460nm actinics for 10 hours and 10,000k and 12,000k daylights for 8 hours. Was battling cyano and some algae so got off the 12 hour cycle and never went back.
