Coralife Ultraviolet Sterilizer Turbo-Twist, size 6x

Purchased for my turtle tank years ago, but never used as I ended up going another route. All parts are included in package. A product description from the Petco website, where the item was originally purchased, is included in the photos so please read thoroughly to ensure this is what youre looking for and is properly rated for your aquarium. While I have not used this specific product from Coralife, I do have personal experience with their other products on the market and this is by far one of the better brands like Fluval and Marineland.
