Hi all.  Just got my new HQI fixture from Hamilton yesterday.  150w double-ended 10,000k Ushio Bulb, 2 75w VHO Super Actinics.  Just have to say awesome light.  I currently have it about 24" from the water.  I know this is way too high but I only had 110w pc over it before.  I dont want to cause too much stress.  What I need to know is how much and how often do I lower the light to eventually reach about 12" above water line.  The tank is a 20L if that makes a diff.  Thanks.
