Seems to be working as advertised
December 15, 2013
I have had this installed for only a week now.. So it seems to be working as needed, but I can't really comment on longer term effectiveness. Water is very clear, but it was pretty clear to start. We will see if stays that way. The graphite exterior glass tube housing arrived with a crack/chip in it, but it was below the rubber grommet that seals the bulb so I installed it anyway -- Apparenty, no problem
Pros:Price. Ease of installation.
