			 I have a 90 gallon with LPS and SPS.  2-250watt 10K's and VHO's.  How long should my photoperiod be? 
		
	
		
		
		
		
		
	
		
		
	
	
	Right now my VHO's come on at 13:00 - 2300 and my halides from 14:00 - 22:00.  |

			 That photoperiod sounds okay. If you want to bump you MH up to 10hrs and VHO 12hrs that's fine too.
