Lee’s Slim Gravel Vacuum (12-inch) – A slender-profile siphon cleaner ideal for smaller aquariums or tight spots. Its narrow 12″ long intake tube fits into corners and between decorations to remove detritus without excessive water removal. The Slim Vac is easy to start (just a simple up-and-down motion) and efficiently suctions out waste and uneaten food from gravel, helping maintain a clean, healthy tank for bettas, goldfish, or nano tank inhabitants.
