When upgrading my 55 FOWLR to a 90, I had to move my inline UV sterilizer - an Aqua UV Advantage 8W - and noted it was time to replace the bulb. Long story short, the new bulb doesn't seem to work, but it's unclear whether the problem is the bulb or the transformer / power supply, although I'm leaning toward the latter. Does anyone in the NoVa area have a transformer / power supply for this sterilizer that I could borrow to determine which component of my unit is faulty? Given that the replacement part is half the price of a complete new unit I want to be sure that's really the problem before I do anything else. Thanks!
