Your tank looks very nice!
What brand and type of UVB are you using? Is it a coil UVB or an MVB? If it is an MVB.. what brand and wattage is it?
I did notice your thermometers. Unfortunately, the type you are using are not very accurate for getting direct basking temps. I would suggest getting either a digital thermometer with a long wire and probe end or a temperature gun. Either of these type thermometers will be good.
Walmart carries a digital thermometer with wire/probe called AcuRite. They run around $12 and can be found in the home thermometer section of the store.
The temp guns can be found at places like Harbor Freight or any automotive store. You can easily get them online as well.
