			 He has a phillips ballast right now, but It won't fire up a 10,000k so that's why he needs the new ballast. He is also planning on getting rid of the 3 tubes of attinic when he goe's with the upgrade. Any thoughts?

 http://www.reefcentral.com/vbulletin...e&pagenumber=2 My personal preference would be without actinics because I like my white sand to look white. If you prefer the underwater look, then keep the actinics. The extra light will benefit the animals too.  |

			 Sure, my thoughts are you still haven't answered the questions!! WHY is he going to 10k? Let's assume he has a reason. He will most likley want to keep the actinics. I have 10k, they need actinics. If he has a M59 ballast, it will fire the 10k bulbs. What ansi code is the ballast?

	Radium if you want softy and lps: light green, solid yellow,and brown saki is the cheapest but need more actinic to give same resutl as 10k  |

			 Stephane, it's easy to generalize with this sort fo stuff. Strangely enough, one of the most colourful tanks in town is lit by a 400w iwasaki with 2 vho and 2 no 4' actinics.. Though I can't complain about my colour with the radium!

 No offense, but sometimes I think my lighting is a bit too blue. We are using 2x radiums 400w 20K  |

			 Jeanna, he's talking about Brad Gemmell's tank. Really nice colors under a 65k. 
		
	
		
		
		
		
			You should come by and see my tank after my Radiums get delivered. Not too blue at all. Maybe you'll want to switch ballasts!!!
