Oh and something I don't think anyone else noticed...
Your UV bulb is on the side of the tank shining through the glass?
Sorry, but glass and/or plastic will block/absorb most if not all of the UV
It looks like you have a screen top for your viv, so that makes it easy--just get one of those big $10 clamp lamp fixtures (with the ceramic fixture and the high wattage rating!!!) for the Merc.Vap Bulb, save the clamp for later, and set it on top the screen pointing straight down. Also- intense UV lighting from the side can possibly maybe cause eye damage, the Sun comes from Above... I like to put my MVB in the middle of the tank with the basking/heat bulb on one end, so they have a 'cool' end also and the UV covers in at least some percentage- most of the floor space. Just my $.02
