Tube coolers by Pearl will help both sonics and tube life. They are chemically blackened copper fins that push fit over the tubes - only downside is less glow visible!

One potential problem I have heard of is cockroach infestation, their droppings are corrosive.
Otherwise, the other two posts cover it!
