I was just wondering I have a repti glo 2.0 daylight terrarium lamp 18" over my 10 gallon tank that I keep on for about 12hrs. I was just wondering if this is needed and what is the proper way to use it? The guy at the local petstore said it would make the coloring of the leo brighter and prettier, I just wanted to here what are your thought on this? I also am using a 60 watt zoo med blue bulb a few hours less than the repti glo because it gets to hot so I am going to switch to a red 40 watt bulb, Is a red bulb ok to use during the day?
