I'm wondering if UV light breaks or weakens silicone of the aquairum?

Are you shining UV on silicone or rather thinking about a reactive species generated by UV damaging silicone?

not many materials are UV resistant. Check your silicon around your window outside how they end up drying and cracking in the sun after a few years. That should give you a hint.
